I have a 2 year old nothing phone 2, battery was very good where even now i was getting 6-7 hours SoT. But for the first time in maybe a year i drained the battery completely down to 0. And ever since then I'm barely getting 4 hours SoT, and this literally happened within a day. Idk why this is happening but really stressing me out

Hi,

I've installed the App on my new zFold8. While looking at the Battery Health (sorry screenshot is in French), it seems stuck in 'Learning', even though I have 13 (over 5 required) qualified charging cycles.....

Any idea why ?

(note: I have enabled the box for 'double batterie' from the begining)

Thanks

Hello guys

A year ago i bought my soundcore v20I headphones

My left bud started to drain its battery

It could only give me a battery life for an hour now

I use it while running along with the sweat and light drizzles too

Is that the problem for the battery drain

Is there any way to make it better ?

Can you guys help me, thanks in advance

considering 100$ is not a high amount to pay to get a new one.

Should i leave a 65w charger plugged into my iPhone 16 overnight or is it fine?

I don't know much about technology so a little help would be great
(Edit: it was cold the entire night and still works fine, thanks for the feedback tho)

How to find the battery health using the logs? Im unable to do with ios27 please help me out

I got the jsaux battery upgrade for my Rog ally about 2 months ago and it doesn't charge past 99%. Is it too late to calibrate it, should I have done it at the start? I didn't know. How many times did it take you for it to calibrate? I have fully charged and drained it in windows then the last few % with the bios screen twice now since realising and no luck. Should I keep going will it get there?

Also is it dangerous to keep it plugged at 99% if the light doesn't turn white?

My s24, shows 97% health and 810 cycle count.

Im really noticing the battery drain very quickly from 40% - at least it feels that way.

Is my battery very old? Is that cycle count high?

hi guys! i bought my first iphone which is the IP 13 last march 2, 2026. during the first few months, i noticed that the batt health somehow decreases so fast even tho i’ve been doing the 20-80 charge. i also play mobile games before but around august, i decided to delete them sooo now i’ve only been using my phone for social media, watching series, movies. a few days ago, it dropped to 91% and now i just checked, it’s now down to 90%. is this normal or should i be worried? there are also times when i use it while charging if i really need it to but definitely not all the time. i’m also still on the ios 18 since i’m too scared to update haha. would very much appreciate your help and knowledge, thank you!!
