The Reno 7 battery model name, as a parts listing gives it for the 5G phone, is BLP855, and the pack is listed at 4500 mAh typical. A single listing gives BLP855 for the Reno 7 5G, so treat it as a firm lead. The same listing names the Reno 6 Pro 5G as a second phone that takes this pack.

People type this as "oppo reno 7 battery model number" or "reno 7 battery model number", but the battery code and the phone's model number are two different things. The Reno 7 5G's own model number is in Settings. BLP855 is printed on the cell sticker, visible only once the back is open. Always bring both to the counter.

Step by step

  1. Find the exact Reno 7 version you own

    Open Settings, tap About phone and note the device name and model number. If it is not on the first screen, type model in the Settings search bar. The retail box also carries the same number on its label.

  2. Have the back opened by a technician

    The Reno 7 is a sealed phone. Do not heat the back or pry it yourself. A technician can open it safely and show you the sticker on the cell.

  3. Read the code, capacity and voltage on the sticker

    Look for a code starting with BLP, then the mAh and voltage lines. Compare it with BLP855 and note any difference, even one character.

  4. Photograph the sticker before the pack is removed

    One clear photo saves a second trip if the first pack does not match. Tilt the phone so the print does not glare.

  5. Compare the new pack side by side

    Check the code, the connector shape, the size and the weight against the old pack before it goes into the phone.

Reno 7 battery model name: the code and its twin

Oppo uses the BLP prefix for cells in Oppo, Realme and OnePlus phones. BLP names the maker group, and only the full BLP855 points to the Reno 7 5G. For the Reno 7 5G, the listing names BLP855. That listing also includes the Reno 6 Pro 5G, suggesting both phones share BLP855.

5G, 4G or Pro: know which Reno 7 you hold

The name Reno 7 covers more than one phone. The 5G model sold in India is a 4500 mAh phone with 65W charging. A 4G version also exists with a different model number, and a Pro model sits above both. Each version can carry its own pack, and a 4500 mAh figure on two phones does not make the packs interchangeable.

Look at the model number first. If it is CPH2371, the BLP855 lead applies. If it is anything else, do not use this code until a technician has read the sticker on your cell.

An owner asked for a Reno 7 pack and the counter pulled out one made for the Reno 7 Pro, since both boxes said Reno 7. The technician checked the Reno 7 5G's model number in About phone and then the sticker with the back open. The codes differed, so the spare went back to the shelf.

How many mAh is the Reno 7 battery

Oppo's Reno 7 5G specifications quote 4500 mAh typical, the BLP855 figure. Expect the BLP855 sticker to add a rated number a little under 4500 mAh. That rated figure is unconfirmed for the Reno 7 5G, so read it from your cell.

BLP855 watt hours equal mAh times the sticker voltage, over a thousand. With BLP855's voltage unconfirmed, read it off your own sticker. Capacity alone does not predict Reno 7 5G runtime. Screen time follows its AMOLED display, refresh rate, signal and apps.

On the 5G model, the 65W charger moves the pack from low to full much faster than an ordinary 18W unit. That speed produces heat, so keep the phone out of a thick cover while it charges.

Where the code is printed on a Reno 7

You will not find the battery code in Settings. The Reno 7 5G shows its model number and, on some builds, a battery health page, but BLP855 appears only on the cell. It can also appear on spare part listings and service job sheets.

  • Reno 7 box label: the phone model number, not BLP855.
  • About phone: shows the model number, which tells the 5G from the 4G.
  • Cell sticker: shows the BLP code, capacity and voltage. Reaching BLP855 means a technician opening the back.

Signs the Reno 7 battery is wearing out

How a Reno 7 battery shows wear and what to do

Reno 7 5G charges slowly and runs warmCable, charger or cell faultTry the original charger, then get it tested

Heavy apps and weak network often look like a bad battery, so read about fast battery drain before you blame the cell. Then follow the health check guide and decide.

If the Reno 7 back lifts, the screen bulges, or it gets very hot or leaks, unplug it immediately. Never press, bend or puncture the Reno 7, and move it away from warmth. Cheap BLP855 copies often print false capacities, so fit only a pack matching your old label.

Buying and fitting a replacement pack

Bring the technician the Reno 7 5G model number, the code you read and your photo of the old label. Ask for a pack with the same code and the same connector. Another 4500 mAh code may not fit the Reno 7, however close it looks.

These signs point to a weak copy:

  • It is lighter than the BLP855 that came out.
  • BLP855 lettering is smudged and lacks a batch line.
  • It claims far beyond 4500 mAh. No Reno 7 sized pack can honestly hold that.

Because the Reno 7 5G is sealed, a trained person should open it. The general steps are in the replacement guide.

After the swap, ask the technician to charge the phone once in front of you. If it runs hot within minutes, say so before you leave.

Keeping a 65W phone's battery healthy

Fast charging suits a quick top-up, but heat is the real enemy. Do not charge on a bed or in sunlight, and take off a tight case when the phone feels warm. Charge the Reno 7 5G with its 65 W boxed adapter, since a poor cable can heat at the plug.

Leaving the Reno 7 plugged in overnight every day ages BLP855 faster. Unplug near full when you can, and avoid running it down to zero again and again. For a wider view, the family list of Oppo battery codes shows how other Reno and A series packs compare, including the Reno 8.

Frequently asked questions

What is the Reno 7 battery model name?

One parts listing gives BLP855 for the Reno 7 5G, at 4500 mAh typical. With one listing only, read BLP855 off your own cell before ordering.

Which battery code does the Reno 7 use?

Its cell code is BLP855, according to one listing. The phone has a separate model number in About phone, which for the India 5G model is CPH2371. Do not mix up the Reno 7 and Reno 6 Pro when asking for a pack.

What capacity does the Reno 7 battery have?

The 5G model is listed at 4500 mAh typical. Expect the BLP855 label to show a rated minimum a touch below 4500 mAh.

Does the Reno 7 4G use the same battery as the 5G?

Do not assume so. The Reno 7 4G carries another model number, and its cell code is unconfirmed here. Read the label on the Reno 7 4G's old cell.

Can I use a Reno 7 Pro battery in a Reno 7?

No match is confirmed, so the safe answer is no. The two phones are different models, and a pack with another code may not fit the connector.

Can I change the Reno 7 battery at home?

As a sealed phone, the Reno 7 5G is best left to Oppo service or a shop you trust. Heat or force on a sealed phone can damage the cell.
