The BLP727 battery model name sits on the 5000 mAh pack inside the Oppo A5 2020 and A9 2020, according to the parts sellers who list it by Oppo model number. A few listings add the Oppo A11x and the China-only A11, and one quotes 4900 mAh, which fits the usual minimum printed under a 5000 mAh advertised figure.
Searchers often land here while looking for a Realme battery, because BLP727 and the Realme code BLP729 differ by one digit. They are separate packs.

BLP727 and BLP729 are not twins
One digit apart, two different phones. BLP729 is the Realme 5, 5i, C3, C11 and C21 pack. Oppo's A5 2020 and Realme's 5 came off related production lines in the same season and both pack 5000 mAh, a coincidence that keeps tripping up spare part counters. Nobody promises the outline and flex cable line up, so a counter that offers "either one" is guessing.
Ordering the pack without mistakes
- Write the CPH model number from the phone, not just "A5".
- Ask for BLP727 by code and check it on the new cell's sticker.
- Expect 5000 mAh typical or 4900 mAh minimum on the label, never 6000.
- Hold on to the original BLP727 until the replacement has been through one complete charge cycle in your phone.
Years have passed since the A5 2020 launched, and plenty of first-fit BLP727 cells are now puffing up. A screen that lifts at one corner is the usual sign. Stop charging, do not press the screen down, and have the cell taken out promptly.
Energy and charging on BLP727
At a typical 3.87 V, BLP727's 5000 mAh works out near 19.4 Wh. Both phones came with a 10 W USB C brick, so an empty BLP727 needs roughly two and a half hours on the wall. If that time halves after a swap while using the same brick, the fresh cell probably stores less than its sticker promises.
Is it worth replacing
For a phone that still runs your apps well, a new pack is the cheapest way to get back a full day of use. Rule out software drain with our fast drain checklist, then book an Oppo service slot or a repairer whose work you know.
What changes after a new BLP727
A fresh pack in an A5 2020 or A9 2020 brings back the long standby these phones were known for: a lightly used unit can sit for two days between charges again. For a few days the percentage readout can behave strangely as the phone learns the new BLP727; give it one charge to full and one run down to low before you decide anything. After that, the percentage should drop smoothly. Big ten point jumps after that usually mean the flex connector is not pressed home, which the fitter can fix in minutes.
