Cell Phone and Tablet Battery Replacement
A battery that drains quickly, shuts down unexpectedly, or no longer lasts through normal daily use can make an otherwise working device difficult to rely on. CELLTECH provides battery replacement services across Dallas and El Paso for supported cell phones and other devices.
Need your device working properly again today? You do not need to determine whether the battery is causing the problem yourself. Bring your device to a CELLTECH store, explain what is happening, and we can inspect the symptoms before explaining the available repair options, expected repair time, and price.

Phone repair, in store
I dropped it in the car park on a Tuesday morning and had written the phone off in my head by lunchtime. They took it in, quoted me on the spot and handed it back the same afternoon with the old panel in a bag so I could see what had actually broken.

iPhone 14 Pro screen repair
It was down to twenty percent before lunch every single day and I assumed I was being sold a new battery whatever I said. They tested it in front of me first, showed me the health reading, then swapped it and had me out inside the hour.
Tomas G.
Galaxy S23 battery replacement
I put a full cup of coffee across the keyboard and had four years of work on there with no backup. They opened it the same day, cleaned the board properly rather than just drying it out, and every key on it still works months later.
Priya N.
MacBook Air liquid damage
The last place I used quoted one number on the phone and a different one at the counter. These people looked at the port, told me what it would cost before they touched anything, and that was exactly what I paid when I collected it.

The back was shattered end to end and pieces of it were coming away in my hand. I left it with them on my lunch break, came back after work, and there is no seam and no gap anywhere on it. You would not know it had happened.

Pixel 8 back glass repair
What actually decided it for me was the 90 day malfunction warranty, because I had been burned by a cheap repair before that failed inside a fortnight. Nothing has gone wrong with this one, but I would have had somewhere to go if it had.

Why CELLTECH
Why Choose CELLTECH for Battery Replacement?
Battery problems do not always mean the battery itself needs replacement. Fast battery drain can sometimes be related to software, charging problems, heavy usage, background activity, or another hardware issue. CELLTECH starts with the symptoms and device before recommending a battery replacement. Choosing CELLTECH also gives you access to fast service and warranty protection after your repair. At CELLTECH:
- Your device can be inspected before battery replacement is recommended.
- Battery related symptoms can be checked.
- The exact device model is considered.
- Repair options and pricing are explained before work begins.
- Parts availability can be checked for your device.
- Walk-ins are welcome.
- Seven staffed CELLTECH stores, most of them inside centers you already visit.
- The goal is to identify whether the battery is actually causing the problem, explain your options clearly, and help you get your device back into normal use as quickly as possible.
What we fix
Signs You May Need a Battery Replacement
Battery performance normally changes as rechargeable batteries age. However, one symptom alone does not automatically mean replacement is necessary. Common signs that your battery may need attention include:
If your device used to last most of the day but now requires charging several times, battery wear may be one possible cause.
Before assuming replacement is necessary, also consider recent software changes, new apps, increased screen time, high brightness, and other changes in device usage.
If battery life remains unusually short during normal use, have the device checked.
A device that switches off even though the battery indicator still shows remaining charge may have a battery or power related problem. Unexpected shutdowns can also have other causes. Inspection can help determine whether battery replacement is the appropriate repair. When the battery is confirmed as the problem, CELLTECH can check:
Battery availability, Repair price
Battery percentage that falls unusually fast during normal use can indicate reduced battery performance. Pay attention to whether the problem happens:
During normal everyday use, While using the camera, During gaming or other demanding apps, When the device gets cold, At similar battery percentages, Shortly after disconnecting the charger
These details can help during diagnosis.
If the device turns off shortly after being disconnected from power, the battery may no longer be supplying power correctly. However, charging and power related faults can produce similar symptoms. The device should be inspected before battery replacement is confirmed.
A battery that reaches a high percentage while charging but loses that charge unusually quickly may be deteriorating. The cause should still be checked because software activity and other hardware problems can also affect battery life.
A battery that loses a large share of its charge overnight, with the screen off and nothing running, is worth checking. You may notice:
A large drop in percentage by morning
Drain continuing in airplane mode, The device warm after standing idle
Background activity alone does not usually explain a very large overnight loss.
An inspection can separate an aging battery from an app holding the device awake.
Rechargeable batteries lose capacity as they age, and most devices can report roughly how much is left. Consider:
How much capacity the device reports, How old the device is, How often it has been charged
A reduced figure on its own does not mean replacement is required.
Reduced capacity together with poor everyday performance is the combination worth acting on.
Some devices reduce peak performance when a battery can no longer supply power steadily. You may notice:
Apps taking longer to open, Stuttering during normal use, Performance improving while plugged in
Software and storage can produce similar symptoms, so the battery should be confirmed rather than assumed.
If the battery is the cause, replacement can restore normal everyday performance.
Slow charging does not automatically mean you need a new battery. Possible causes can include:
Slow charging can come from the cable, the adapter, the charging connection, device temperature, software activity, or the battery itself.
If charging remains unusually slow with a compatible charger and cable, the device may need inspection.
Heat
Battery Getting Hot or Device Becoming Unusually Warm
Devices become warm during charging, gaming, video recording, navigation, updates, and other demanding tasks. Unusual heat alongside poor battery performance, unexpected shutdowns, or charging problems should be checked.
- Heat while the device sits idle
- Heat concentrated behind the battery
- Charging pausing until the device cools
A case that no longer sits flat
If the device becomes excessively hot or appears physically damaged, stop using it and arrange professional inspection.
If battery replacement is required after inspection, the store can confirm battery availability and repair time.
Swelling
Screen Lifting or Battery Swelling
A screen or rear panel beginning to separate from the device can indicate pressure from a damaged battery. Other causes can also include:
- Frame damage
- Adhesive failure
- Previous repair issues
- Physical impact
If battery swelling is suspected, stop using and charging the device and arrange professional inspection.
Do not press a lifting display or rear panel back into place.
A swollen battery is treated differently from a routine replacement because the device must be assessed first.
Once inspected, CELLTECH can explain the available repair option and turnaround.
iPhone
iPhone Battery Replacement
CELLTECH provides battery replacement options for supported iPhone models.
Reduced Maximum Capacity under Battery Health, A battery service message in iOS, A Peak Performance Capability notice, iPhone shutting down while charge remains
iPhone needing a charge more than once a day
Poor performance alongside an aging iPhone battery
Supported iPhones provide battery health information within iOS. Battery health information can help you understand how the battery has aged, but the percentage should be considered together with actual everyday performance and device symptoms. If your iPhone battery is performing poorly, CELLTECH can inspect the device and explain the available battery replacement options. The store can also confirm:
Battery availability, Repair price
Supported iPhones can display information about replaced components under Parts and Service History. The information shown can depend on the iPhone model, replacement battery, software version, and repair process. Before approving service, you can ask:
What type of battery is being installed?
Is any repair configuration required?
Does Battery Health information work as expected for this repair?
Clear information before service can help you understand the repair before work begins.
Samsung Galaxy
Samsung Galaxy Battery Replacement
CELLTECH provides battery replacement options for supported Samsung Galaxy devices.
Device Care reporting reduced battery capacity, Galaxy draining quickly during light use, Galaxy shutting down while charge remains
Galaxy needing a charge more than once a day
Battery percentage falling unusually fast on the Galaxy
Charging problems alongside poor battery life
Compatible Galaxy devices can provide battery diagnostic information through Samsung Members. This can help identify battery status before repair. You do not need to complete diagnostics before visiting CELLTECH. If the device cannot be used normally, simply bring it in and explain the symptoms. If replacement is appropriate, CELLTECH can confirm:
Correct Galaxy battery, Parts availability, Repair cost
Other devices
Battery Replacement for Other Devices
CELLTECH can provide battery replacement or repair options for supported device models. Availability depends on the exact model and replacement battery.
01
Google Pixel Battery Replacement
Availability can vary by Pixel model and the parts on hand, so bring the device in or contact your nearest CELLTECH store first. Common reasons to have a Pixel battery checked:
Pixel shutting down while charge remains
- Pixel draining faster than it used to
- Adaptive Battery no longer stretching the day
- Availability depends on the exact Pixel generation and its replacement battery.
02
Other Android Cell Phone Batteries
Battery replacement may be available for supported devices from manufacturers such as Motorola, OnePlus, LG, and other Android brands. Common reasons to have one checked:
Android phone draining during light use, Phone shutting down while charge remains, Battery percentage falling unusually fast
- Once the model is identified, CELLTECH can check replacement battery availability and the repair price.
03
Tablet Battery Replacement
Options may be available for supported Apple iPad models, Samsung Galaxy tablets, and other Android tablets. Common reasons to have a tablet battery checked:
Tablet shutting down while charge remains
- Tablet no longer lasting a full day
- Tablet charging far more slowly than before
- Tablet batteries can need more disassembly than a phone, so the turnaround can differ.
A device that does not charge does not automatically need a new battery. The problem may involve:
- Charging cable
- Power adapter
- Charging port
- Debris in the charging connection
- Battery
- Charging circuitry
- Another hardware component
- Signs the charging system may need attention include charging only at certain cable angles, a cable that repeatedly disconnects, a loose charging connection, a device that does not recognize a charger, and wired charging failing completely.
- These symptoms do not confirm a damaged charging port, but they provide useful information during inspection.
- CELLTECH can inspect the charging behavior before recommending battery replacement.
Battery or software
Battery Replacement or Software Problem?
Fast battery drain can sometimes happen even when the battery itself is still usable. Before visiting, consider whether the problem started after:
- Installing a new app
- Installing a software update
- Increasing screen brightness
- Using navigation more frequently
- Gaming or streaming for longer periods
- Changing network conditions
- Using the camera heavily
- Running more apps in the background
- If battery performance remains poor during normal use, professional inspection can help determine whether replacement makes sense.
How it works
How a CELLTECH Battery Replacement Works
1. Tell Us What Is Happening
Tell us what the device is doing: fast drain, unexpected shutdowns, a percentage that jumps, or a phone that only works while plugged in. Walk-ins are welcome, so no appointment is needed.
2. We Inspect the Device
We check the device against the symptoms you describe, because a battery complaint is not always a battery fault. Charging hardware, software and ordinary daily use can produce the same pattern.
3. We Explain the Battery Replacement and Quote
You get the battery part type, the price, the expected turnaround, and any considerations specific to your model, all explained before the battery replacement is approved.
4. You Decide
You decide whether to go ahead. The replacement starts only once the work and its price have been explained, and many battery replacements are finished during the same visit.
Pricing
How Much Does Battery Replacement Cost?
There is no single battery replacement price that applies to every device. Cost can depend on several factors.
Different devices use different batteries, internal layouts, adhesives, and repair procedures. The exact model is needed to identify the correct replacement battery.
Replacement battery availability can vary between current, older, and less common device models. Battery availability can also determine whether the repair:
Requires additional ordering time
Some batteries require more disassembly to access than others. This can affect the repair process and turnaround. A routine cell phone battery replacement may be faster than a tablet or device with a more complex internal design.
The type of replacement battery affects both the price and what you can expect afterward. Ask what is being installed, whether it is new, and how it is expected to perform against the battery it replaces before the repair is approved.
Price can move in both directions with age. A very recent device can carry a higher battery cost while supply is still limited, and a much older model can cost more when the correct battery is harder to source.
CELLTECH inspects the device and explains what is wrong before anything is agreed. You hear the replacement option and the price first, and you can decide not to continue. Asking what is included, and what happens if further damage is found, keeps the final figure predictable.
Battery replacement may be more complicated if the device also has:
Cracked screen, Damaged frame, Liquid damage, Charging problems, Previous internal damage, A lifting display or rear panel
Additional damage can affect both repair price and repair time.
CELLTECH provides a quote after confirming the device and required repair.
Turnaround
How Long Does Battery Replacement Take?
You may not need to spend the entire day without your device. Many common CELLTECH battery replacements can be completed in as little as 20 minutes when the correct battery is available and no additional damage is found. Same day battery replacement is also available for many supported devices. Battery replacement time depends on:
- Device model
- Battery availability
- Device construction
- Condition of the device
- Additional damage
- Whether further diagnosis is required
Many common cell phone battery replacements are among the faster repair services.
Some devices require additional disassembly, testing, or parts ordering.
Tablet battery replacement can also require different repair procedures.
Your CELLTECH store can provide a more accurate estimate after confirming your device model.
Repair or replace
Should I Replace the Battery or Replace the Device?
Poor battery life does not automatically mean you need a new device. Battery replacement may make sense when:
- The rest of the device works well.
- Battery performance is the main problem.
- The required battery is available.
- Repair cost is reasonable compared with replacement.
- You are satisfied with the device.
- You want to continue using the existing device.
- Replacing only the battery can also avoid the time involved in buying, transferring data to, and setting up an entirely different device.
- Replacing the entire device may make more sense when several major components are damaged, the device has serious internal damage, parts are difficult to obtain, repair cost approaches replacement cost, or the device no longer meets your needs.
- A battery replacement quote gives you a realistic cost to compare with replacing the entire device.
Before your visit
Before You Bring Your Device for Battery Replacement
A few simple steps can make your visit easier.
If your device is still working, back up important:
Photos, Videos, Contacts, Messages, Documents, Authentication information, Other important files
Battery replacement does not normally require personal files to be removed, but backing up important information before any device repair is recommended.
Knowing the exact model can help check battery availability before repair. If you are unsure which model you have, your CELLTECH store can help identify it. Knowing the model can also help confirm:
Battery price, Battery availability
Device access may help test battery and charging behavior after repair. This can help confirm that the device powers on, charges, and reports battery information correctly.
If the problem happens only with a particular charger or cable, explaining that behavior can help distinguish between battery and charging related issues. Bringing the cable or charger may provide useful information during inspection.
If the device has previously had a battery, screen, charging port, or other internal repair, mention it before service. Previous repair information can help when assessing the current problem.
If getting the device back quickly is important, ask whether the correct battery for your model is currently in stock. Turnaround depends on it more than on anything else.
After the repair
What to Check After Battery Replacement
Depending on the device, relevant checks can include:
- Device powers on normally
- Device accepts a charge
- Battery percentage displays correctly
- Charging connection works
- Device does not shut down unexpectedly
- Screen sits correctly in the frame
- Rear panel sits correctly
- Relevant battery information appears normally
If something does not behave as expected, mention it before leaving the store.
Water resistance
Water Resistance After Battery Replacement
Water resistance is not permanent. It can decrease because of:
- Normal wear
- Physical damage
- Previous repairs
- Device disassembly
- Seal deterioration
Battery replacement usually requires access to internal components.
If water resistance is important to you, ask what sealing process applies to your specific repair.
Do not assume that a repaired device has exactly the same water resistance it had when new.
The 90 day malfunction warranty applies to qualifying repair related malfunctions and should not be interpreted as protection against new liquid exposure or accidental water damage.
CELLTECH battery replacements are backed by a 90 day malfunction warranty. This gives you added confidence after your battery replacement. If the replaced battery develops a covered malfunction during the 90 day malfunction warranty period, bring your device and repair information back to CELLTECH so the issue can be reviewed according to the applicable warranty terms. The 90 day malfunction warranty applies to qualifying repair related malfunctions. New accidental damage, physical impact, liquid exposure, misuse, charging damage caused by unrelated components, or other unrelated device problems may be treated separately. Before approving battery replacement, you can ask:
- What does the 90 day malfunction warranty cover?
- Is the replacement battery covered?
- Is applicable repair related labor covered?
- What problems are excluded?
- Is new accidental damage excluded?
- Is new liquid damage excluded?
- How is warranty service requested?
- Can warranty service be handled at another CELLTECH location?
- Keep your repair receipt and related information after service.

Common questions about
battery replacement.
Straight answers to what people usually ask before bringing a device in for battery replacement.
Common signs include unusually fast battery drain, unexpected shutdowns, needing to charge more often, or poor battery performance during normal use. These symptoms can also have other causes, so inspection can help determine whether battery replacement is appropriate.
Battery drain can be affected by battery age, apps, screen usage, network conditions, software activity, and other factors. If battery life remains unusually short during normal everyday use, have the device checked.
Unexpected shutdowns may be related to battery deterioration, power delivery, software, or another hardware problem. The symptoms should be diagnosed before battery replacement is recommended.
A sudden change in battery percentage can be associated with battery condition or battery reporting. If it happens repeatedly, especially with poor overall battery life or unexpected shutdowns, the device should be inspected.
Not necessarily. Slow charging can also involve the cable, adapter, charging port, device temperature, software activity, or charging hardware. Inspection can help determine whether the battery or charging system is causing the problem.
