When June 2025 update for Nothing Phone (2a) was released it was considerably larger for some minor fixes and security patch with changelog mentioning about fixing battery drain on wifi, but it introduces an annoying bug which cause higher active battery drain and phone heating comapred to previous builds with the similar normal use.
As the Phone (2) received their june patch with 1st july 2025 build, the user are reporting lower battery drain and heating is reduced too, Kuddos to the team but please look after Phone (2a), peace of mind is must, team.
It used to be lower but now it’s around 11-12%/h, and battery temperature is mostly high around 39% in normal usage and increase even futher while have usage. I didn’t face the battery draining ever since I have bought the phone (for around 1 year) and it was all good, but with the latest patch I am facing the problem. And I am not the only one with it.
for reference here are the comments under the firmware post of Phone (2a) V3.2-250620-1021:-
