Searching the BLP883 battery model name leads to the Realme 8s 5G, model number RMX3381, with a pack listed at 5000 mAh typical. The code sits in the BLP family used by the Oppo group, which covers Oppo, Realme and OnePlus. Only one phone is matched to it here, and the match rests on a spare part listing, so your own battery sticker has the final say.
People also type it as "blp 883 battery model name". The space makes no difference, but a single wrong digit does. Codes such as BLP885 and BLP877 look almost the same on a worn sticker and belong to other phones, so read every character before you pay for a pack.
Quick facts
Step by step
Write down the phone name and model number
Open Settings, tap About phone and note the device name. If the model number is hidden, type model in the Settings search bar. A Realme 8s 5G should show RMX3381.
Have the old battery sticker read by a technician
On a sealed phone the back panel must be lifted first. The sticker then shows
BLP883with the capacity and voltage. Leave the pulling and prying to the person doing the repair.Compare the new pack with the old one
Put both packs side by side. The code, the plug shape and the outline should match. Weight should be close too.
Check print quality and batch marks
Good packs carry crisp print and batch details. Smudged text or a capacity far above 5000 mAh is a reason to refuse the pack.
What the BLP883 battery model name tells you
The letters BLP are the mark of the Oppo group. Oppo, Realme and OnePlus all use that BLP prefix. The digits 883 are a part number for one cell design. The digits alone do not name the Realme 8s 5G, and BLP883 is no relative of BLP882 or BLP884.
For this code, a spare part listing names the Realme 8s 5G and gives 5000 mAh. Most listings match it to that phone, but treat the match as probable and confirm it on the sticker. The cell is listed as Li-ion polymer, which is normal for slim phone packs.
Phones linked to BLP883
| Phone | Model number | Status |
|---|---|---|
| Realme 8s 5G | RMX3381 | Matched by a listing, 5000 mAh typical |
| Realme 8 5G | Not checked | Not confirmed for this code, has its own page |
The Realme 8s 5G and the Realme 8 5G have almost the same name but are different phones. Their battery codes need not be the same, so open the Realme 8 5G battery page and compare. When two phones share a name stem, the model number is the safe way to tell them apart.
Rated and typical mAh on a BLP883 pack
Realme quotes 5000 mAh typical for BLP883 in the 8s 5G. Realme labels often add a rated minimum a little lower, the floor every cell must reach. Read both numbers on your own sticker. They may differ from batch to batch.
BLP883 watt hours: 5000 mAh multiplied by the label voltage, then divided by a thousand. A nominal 3.87 V, if that is what your label shows, gives about 19.4 Wh for 5000 mAh. Listings print 4.45 V for this code. That looks like the highest charge voltage, not the nominal one, so do not use it in the sum.
Screen time on the Realme 8s 5G rests on its 90 Hz display, signal, brightness and apps. How fast it charges is set by the charger and cable. Capacity alone settles neither. For other phones in the same class, see the 5000 mAh phone list.
Check before you buy a replacement
A wrong pack costs time even when it looks right. Do these checks in order.
- Confirm the phone is a Realme 8s 5G with model number RMX3381.
- Ask for the old sticker to be read, or photographed, before the pack is thrown away.
- Match all six characters,
BLP883, not only the first three. - Look at the plug and the outline. A 5000 mAh Realme pack under another code may not seat in the 8s 5G.
One customer asked the counter for "a 5000 mAh Realme battery" for an 8s 5G. The counter had a BLP885 pack in hand, which looked the same size. The technician opened the phone first, saw BLP883 on the sticker and sent for the exact code. The extra five minutes saved a second visit.
Look-alike codes people confuse with BLP883
Neighbouring numbers are not related phones. BLP885, BLP877 and BLP875 each have a separate page with their own phone list, so look them up instead of guessing from the digits.
- Worn print makes 3, 8 and 5 hard to tell apart. Tilt the sticker in strong light.
- A Realme phone with the same screen size and battery size may still use another code.
- Listing photos can show a different code from the pack that arrives, so check the pack itself.
Other BLP codes are listed in our Realme and Oppo code index. Another 5G Realme phone, the Realme 9 5G, also has its own entry.
Signs a BLP883 battery is wearing out
| 8s 5G symptom | Why | BLP883 action |
|---|---|---|

Rule out apps and poor signal on the Realme 8s 5G with our drain advice, then follow the health steps.
Swelling, overheating, leaking or a dent make a BLP883 dangerous. Disconnect the Realme 8s 5G, avoid pressing on the cell and get it away from warmth. BLP883 copies often overstate capacity, so buy the exact code only.
Fitting the pack and caring for it
The Realme 8s 5G has a sealed body, and its back must be opened with the right tools and heat control. Leave this to an authorised workshop or a repairer with a good name. Quote the Realme 8s 5G model number and have them match the old BLP883 sticker. General fitting advice is in the replacement guide.
Hold any new BLP883 beside the old one. A weak copy feels lighter, prints blurrily, lacks batch marks or claims more than an 8s 5G sized cell can hold.
Photograph the old sticker before the repair. Should you need another BLP883 later, the code is already noted for your Realme 8s 5G.
Routine care: plug the Realme 8s 5G into its own 33 W brick on a hard desk, never on cushions or in sunlight, and pull off a bulky case once it warms. Long hours at full charge and heat age any cell faster.
