Battery Drain Reports After Update
Despite all this, many users have raised battery draining issues after installing the update. Some people in the OnePlus Community have reported that the battery is draining faster than before even with normal usage. Some have reported that the battery is draining 5-6 percent in 15-20 minutes. However, this is not the case for everyone. Many have normal batteries.
After a major update, the system may consume a little more battery for the first few days and the phone may feel hot. This usually returns to normal within 2-3 days.
What You Should Do After Installing
If you notice battery drain after updating OnePlus 13R, first turn off Smart Charging and Charging Limit. Charge the phone to 100% and leave it on the charger for an additional hour. This calibrates the battery and optimizes the system. If RAM Expansion is on, turn it off too. Try normal use for a few days. In most cases, this will reduce the problem.
If the battery is still very bad after 4-5 days, then report it in the OnePlus Feedback app or post in the community. Overall, this update is quite good. It can be installed for the new fingerprint animation and security patch. However, be a little careful with the battery and do the necessary optimizations.
