The Oppo A5 2020 battery model name is BLP727, according to the parts listings that name this phone, sold at 5000 mAh typical. Those listings put the A9 2020 on BLP727 too, so the two phones look like twins inside. The letters BLP tell you the maker group is Oppo. BLP alone does not identify the A5 2020, which is why the full code matters.
People search for the battery model number or the battery model of this phone and often land on the wrong page, because Oppo has sold an A5, an A5s and an A5 2020 as three separate handsets. This page covers only the A5 2020. A sealed body hides the battery, so the code is easy to read only when a technician has the back open, and the doubts that remain are listed further down.
Quick facts
Step by step
Note the handset name and its model number
Open Settings, go to About phone and note the name and model number. If you cannot see it, type model in the Settings search bar.
Compare with the retail box
The box sticker carries the same model number. A phone sold as A5 2020 should not read A5s or A5 anywhere on it.
Have the old battery label read
With the back panel opened by a technician, look for
BLP727on the sticker. Take a photo of it before the pack is removed.Match the new pack
The new battery should show the same full code, the same connector and a capacity close to the old pack. Lay them next to each other under good light.
Oppo A5 2020 battery model name and where to read it
An A5 2020 offers three places to look, yet only the cell itself shows BLP727. The sticker on the cell itself is the true source. On a sealed phone like this, the sticker is visible only after a technician has warmed and lifted the back panel. Do not try this at home, since the glue and the cell sit very close to each other.
- On the battery: a sticker with the code, the capacity and a batch line.
- Box and Settings: these show the A5 2020 model number, not the cell code. Use them to prove you hold an A5 2020 and not a look-alike.
- In a parts listing: useful for a first guess, but what is printed on your own pack decides.
If you are only buying, send the repair shop a photo of the box sticker first. They can then keep the right pack ready and save you a second trip.
Oppo A9 2020 battery code and other twins
Many readers ask about the Oppo A9 pack after seeing the A5 2020 pack described as an A9 pack too. The listings seen for this code name both phones together, and both are sold as 5000 mAh handsets, so the match is believable. That is a listing match, not an Oppo statement.
| Oppo handset | Status | What to do |
|---|---|---|
| Oppo A5 2020 | Named in listings for BLP727 | Check the old BLP727 sticker to confirm |
| Oppo A9 2020 | Named in the same listing | Confirm on its own label |
| Oppo A5s | Different phone | Use its own page |
| Realme 5 | Not confirmed for this code | Check its own page |

How many mAh is the Oppo A5 2020 battery
Oppo quotes 5000 mAh for the A5 2020. Adverts and parts sellers use that typical figure. The rated (minimum) figure is usually a little lower and is printed on the sticker of your own pack, so read it there instead of trusting a round figure.
Watt hours need a voltage. Voltage for this pack is not confirmed here, so look for it on your label. Multiply that voltage by BLP727's mAh and divide by a thousand. An A9 2020 pack at another voltage stores different energy even at 5000 mAh, so never compare capacity alone.
An A5 2020 on a healthy BLP727 normally covers a whole day of calls, chat and video. A5 2020 screen time still shifts with brightness, signal and open apps. To see how other phones with a pack of this size behave, read the 5000 mAh phones page.
Phones and codes that cause wrong A5 2020 orders
Oppo names are the main trap. The A5 2020 sits near the A5s, the A31 and the A9 2020 in the catalogue, and the names differ by only a letter or a number. Each of those has its own battery, so a pack that suited one phone can be wrong for the next.
- The Oppo A5s is an older and smaller phone with its own code.
- The Oppo A31 is another phone from the same period, again with its own code.
- BLP731 and BLP727 differ by two digits in the middle, and the pair is easy to misread on a smudged sticker.
- The Realme 5 is a 5000 mAh phone as well, but equal capacity proves nothing about the code.
A customer brought an A5 2020 with a pack that died by afternoon and asked for "the A5 battery". The counter had a smaller pack made for a different A5. The technician held it beside the old cell, saw the codes and the sizes disagree, and sent for BLP727 instead.
When the pack is wearing out
| What you see | Probable reason | Next move |
|---|---|---|
| A5 2020 loses half its charge within hours of light use | BLP727 now holds far less | Test A5 2020 health, then plan for BLP727 |
| A5 2020 turns off while showing a fair charge | BLP727 voltage drops under load | A service desk can measure BLP727 |
| A9 2020 back or screen edge lifts | BLP727 has swollen | Unplug the A5 2020 and go today |
| Phone feels hot while idle | Faulty pack, stuck app or damaged charger | Restart, remove the cover, test with another cable |
On an A5 2020, check apps and reception with our drain checks before suspecting BLP727. If the problem remains, the battery health check page shows how to judge the wear.
If BLP727 bulges, overheats, leaks or is dented, it may catch fire. Unplug the A5 2020 right away, keep it unbent and unpierced, and away from heat. BLP727 knock offs often claim far beyond 5000 mAh, impossible at this size, so accept only the full code.
Getting a new pack fitted
Because the back is sealed, the swap belongs with an Oppo authorised service centre, or else a trusted repair shop. Tell them the handset name, the number printed on the box and the code BLP727, and have them match it against the old sticker before that pack goes in the bin.
A genuine BLP727 has crisp print, a batch line and nearly the old cell's weight. A pack that feels light, has fuzzy letters or promises far more than 5000 mAh should go back. Also ask whether the back adhesive is being renewed, since a loose panel lets in dust and moisture.
General fitting advice for sealed phones is collected in mobile battery replacement, and every Oppo family code is listed on the Oppo battery list.
Daily care for a five thousand mAh pack
BLP727 charges slowly on the 10 W adapter, so many A5 2020 owners leave it plugged in all night. That habit, together with heat, ages the cell faster than hard use does. Give the A5 2020 a shaded, solid surface for charging and lose any bulky cover once it gets warm.
Pair the A5 2020 with its boxed 10 W charger and cable or a decent unit rated no higher. Throw away a cable if its plug gets hot or wobbles. Unplug the A5 2020 when nearly full rather than holding it at 100 percent for hours.
Frequently asked questions
What is the Oppo A5 2020 battery model name?
Parts listings give BLP727, sold as 5000 mAh typical. BLP727 printed on the cell is final proof, and a technician can read it with the back off.
Which battery code does the Oppo A9 2020 use?
The listing that names the A5 2020 also names the A9 2020 for BLP727. Treat that as a likely match and check the BLP727 label in your own phone.
Is the battery model number of this phone the same as the Oppo A5s battery?
No. The A5s is a different, smaller phone with its own cell code. Do not order by the word A5 alone.
How many mAh does this phone's battery have?
Listings show 5000 mAh typical. BLP727's rated minimum is printed on the cell and may be slightly lower.
Can a different 5000 mAh code go in the A5 2020?
Not safely. Equal capacity does not mean equal size or connector. Match all of BLP727 and check the plug before fitting.
Can I replace the A5 2020 battery at home?
Better not to. The A5 2020 back is glued over the cell, so leave it to Oppo authorised service or a trusted shop.
