The Oppo A53 battery model is BLP805, and almost every listing gives a typical capacity of 5000 mAh with a rating of 3.87 V. Listings tie this code to the A53 with model numbers CPH2127 and CPH2131. Most listings also give the same pack to the A53s and A54 4G, so one code covers a small family of Oppo phones.
This page is about the 4G Oppo A53. The A53 5G and a much older phone with a similar name are different handsets, and their batteries are not covered here. BLP805 is printed on the A53 cell's own label. The A53 is sealed, so that label appears only once a technician lifts the rear cover.
Quick facts
Step by step
Find the phone name and model number
Open Settings and go to About phone (some software versions say About device). Write down the name and the number that starts with CPH. If you cannot see it, type about in the Settings search bar.
Compare with the box label
The retail box carries the same CPH number on a white sticker. If the box and the Settings page agree, you have the right phone name for the repair counter.
Have the old battery label read
When the back is open, have the code on the old pack read out. It should say
BLP805. Take a clear photo of the sticker.Match the new pack before fitting
The new pack must show the same code and the same connector shape, and it should weigh about the same as the old one. Keep both on the counter side by side.
How to see the Oppo A53 battery model on your own phone
Oppo does not show the battery code in Settings. Settings gives you only the handset name and its CPH number, and you use those to look up the code. The code itself, BLP805, is printed beside the capacity and voltage on the pack's sticker.
The back of this phone is glued, so reading that sticker means opening it. Leave that to a technician. Your own checks are simple: confirm the CPH number on the box or in About phone, then ask that the old sticker be read aloud before any new pack is chosen. The guide to finding the battery model name follows the same routine for other handsets.
Snap the old sticker with your phone camera before the pack goes into the scrap tray. It settles any argument if a different code arrives later.
Which Oppo A53 do you have: 4G, 5G or older
The name A53 has been used more than once, and this is where wrong orders start. The 4G phone with CPH2127 or CPH2131 is the one matched to BLP805. The A53 5G is a separate phone, and no confirmed code for it is given on this page. An older handset also carried the A53 name long before.
Ask yourself three things: does the box say 4G or 5G, does the model number start with CPH21, and was the phone bought in the last few years? If any answer is unclear, check About phone for the CPH number and have the old sticker checked.
An owner asked for an A53 battery, and the shop table held two packs of the same size from two different phones. The repairer read BLP805 off the old sticker, picked the pack carrying that exact code and put the other one aside before the cover was glued back.
What 5000 mAh means for this pack
A53 adverts and listings say 5000 mAh, the typical figure. Oppo may print a slightly lower minimum on the BLP805 sticker. The rated figure for BLP805 is not confirmed, so look for it on the pack in your hand.
Energy in watt hours is capacity times voltage, then divided by 1000. With 3.87 V as listed, 5000 mAh comes to roughly 19.4 Wh. A 5000 mAh BLP805 and another 5000 mAh pack at a different voltage do not store identical energy, so read both lines.
Running time in daily use depends on screen brightness, mobile signal, the apps you open and how worn the cell is, not only on mAh. A healthy A53 pack of this size usually carries light to moderate use through a day, and a worn pack will fall short of that.
Buying a replacement without getting a fake
BLP805 is one of the most copied codes, because so many phones use it. Many packs sold under this name hold far less than they claim. Hold the new BLP805 beside the A53's old cell before money changes hands.
- Weight: a pack that feels clearly lighter than the old one is a warning sign.
- Print: letters should be sharp and the code should read exactly
BLP805, not a similar code. - Markings: look for batch or manufacture marks. A plain sticker with nothing else is a poor sign.
- Claim: anything promising well above 5000 mAh for this size is not honest.
Ask for the fitting at the brand service centre or at a repair shop you already trust, and check the connector before the cover is closed. The steps in mobile battery replacement cover the rest.
A bulging, very hot, leaking or dented cell is a fire risk. Disconnect the A53 at once, resist pressing on the swelling, park it away from warmth and hand it to Oppo service before evening. Copies printed with inflated numbers are everywhere, so accept only a pack that reads BLP805 exactly.
When the A53 battery starts to fail
| A53 problem | Probable cause | BLP805 step |
|---|---|---|
| Charge level falls fast | Aged cell or a busy app | Test with the battery health check |
| Sudden switch off in the teens or twenties | Cell too weak for peak load | Get the pack tested |
| Display rises from the frame | Swollen pack | Stop charging and get it opened soon |
| Warm even when idle | Fault or a stuck app | Restart the A53, check apps, then get it seen |
Before blaming the cell, read the common causes of fast battery drain, since weak signal and background apps explain many cases.
Care habits for a 5000 mAh pack in daily use
Warmth and many hours at a full charge wear a cell sooner. Keep a charging A53 off mattresses, out from under pillows and out of bright sun. If it runs warm on the charger, take off the cover. Use the A53's boxed adapter or a dependable one rated similarly, and bin any lead that warms at the plug.
A full overnight charge now and then does no harm, but doing it every night keeps the cell topped up for hours. Pull the plug near full when you can. The Oppo battery list helps if you later want to compare this pack with other Oppo codes.
Frequently asked questions
Which battery code does the Oppo A53 use?
Most listings give BLP805 for the Oppo A53 with model numbers CPH2127 and CPH2131. Listings show a 5000 mAh typical pack. The BLP805 print on your own cell is what confirms it.
How many mAh is the Oppo A53 battery?
The typical figure is 5000 mAh, listed at 3.87 V. That is about 19.4 Wh. Expect the A53 label's minimum figure to sit a little below 5000.
Is the Oppo A53 battery the same as the A54?
Most listings show BLP805 for the A53, A53s and A54 4G, so the pack is shared. Write down the CPH number and the old BLP805 print before ordering.
Can I change the Oppo A53 battery at home?
It is a sealed, glued phone, so a home repair risks damage to the pack and the screen. An Oppo service point, or a repairer you have used before, is the safer place to go.
Does the Oppo A53 5G use BLP805?
That is not confirmed here. The A53 5G is a different phone, so find its code from the sticker on its own battery before buying.
How do I know a BLP805 battery is fake?
A copy is often lighter than the original, has dull print, lacks batch marks and promises a huge mAh number. Set it beside the A53's original pack and check them against each other.
