Phone (3a) Series Battery Life Discussion

AyushKumar_JZuatP7eh3 · 2025-03-20T12:56:24+00:00

I recently purchased the Nothing Phone 3a and have noticed that the battery drains very quickly during WhatsApp video calls. Even with a full charge, the battery percentage drops significantly within a short period. Is anyone else experiencing this issue? Are there any settings or optimizations that could help reduce battery consumption during video calls? Any suggestions would be appreciated!

It’s like coming to a doctor and saying how you have particular issues but are refusing to say anything about those issues - no one can help you if you don’t post screenshots of battery usage.

Settings > Battery > Battery usage, set to “View by apps”, screenshot and post here, change to “View by systems”, screenshot and post here.

I won’t go as far to Say “it is GREAT!”

Please Note 28% still left as of now.

And I won’t go below 10% so more 2 hrs of Screen on time left.

Theoretical for my use case around 12+ Hrs.

But if there is significant gaming and video playback then Good Enough for A Day and can be Stretched to 1.5more.

Brightness/Dark Mode and Ambient Temp are also a few factors to consider.

Since the Screen is considerably bigger.

Absolutely Right. I have purchased last one month only but same issue faced. The Battery is fery fast drain.

I’m confused at this point. After the latest update (Asteroids-V3.1-250610-1841), sometimes it drains up to 20% overnight, sometimes it loses only about 5%, I have no idea why. Before the update it always drained around 20%, so I guess I’ll just wait.

I purchased the 3a in April, and while I’m generally happy with its performance and camera quality, I’ve been facing issues with the battery life. After about a month of use, I noticed that the battery has started draining quite fast—even when the phone is idle. It loses around 1–3% every few hours without any usage, including overnight while I’m sleeping.

I’ve already tried several solutions based on community discussions: I’ve reduced the brightness of the Glyph lights, turned off background processes, disabled vibrations, and taken other battery-saving measures. Despite these efforts, the battery continues to drain faster than expected.

Considering it has a 5000 mAh battery, I had hoped for better battery performance. For example, today I was booking an Uber in daylight and noticed the phone got a bit warm (which I understand is normal), but the battery dropped by around 6–7% in just 15 minutes.

My previous phone, a Motorola device with the same 5000 mAh capacity, lasted significantly longer under similar usage. I really don’t want to regret my decision to buy this phone, as I otherwise like it a lot.

Could you please advise if this is a known issue or if I should wait for a software update that might improve battery performance?

Hi everyone,

I have been using the Nothing Phone 3a for the past 4 days. Everything was working perfectly. Performance and battery life were great. I also bought an Anker 313 Ace 2 45W charger, which was charging the phone in about one hour. This charger supports PPS charging and can deliver 21 volts, which is required for the Nothing Phone 3a to achieve rapid charging. There were no noticeable battery issues. Overnight drain was around 1 percent.

Yesterday, I wanted to check exactly how long it takes to charge the phone from 0 to 100 percent. So I let the phone drain completely until it shut down, then charged it fully. Ever since that charge cycle, I have been experiencing battery drain while the phone is idle.

Now the phone is draining 7 to 10 percent overnight even when it is not being used. This never happened before. Also, during the day when I keep the phone in my pocket while I am out and busy, it still loses charge much faster than before, even though I am not actively using it.

If I use the phone continuously, I still get the expected screen-on time. So the issue seems to be related only to idle or standby drain.

Some details:

Phone: Nothing Phone 3a
Charger: Anker 313 Ace 2 45W with PPS 21V support
Software: Nothing OS Build Version Asteroids V3.1 250610 1841 IND

Issue started only after a full 0 to 100 percent charge cycle

Could this be a battery calibration issue? Should I try draining it to 0 percent and charging it to 100 percent again? Has anyone else faced this?

Any help would be appreciated. Thanks.

Hopefully 3.2 update comes fast and fixes the battery issue

My battery is at 94 percent and most of them is gone because the software isn’t optimised properly please look forward into this issue
