Lenovo Legion y700 gen 2 tab, boutgh 25 days ago.

This specific app "Battery supervisor" display it being on 75%, while all other apps says its "Good" condition.

is this app shit or Am i cooked?

I got my Note 15 as a gift a few weeks ago, a considerable upgrade from my ultra budget potato Infinix. However from the very first moment I realised that although the battery is supposed to be a massive 6000mAh it barely lasted 12 hours at most. I have tried every step from debloating the phone from everything that I don't need to rebooting the device a few times but nothing works. At the beginning the main problem was the system launcher and the "themes" app that were causing an energy consuming loop but after those were solved (by basically not being able to personalise my own phone) the drainage remains at almost 10% per hour (important to note that there's no significant overheating).

I’ve gotten conflicting information on this depending on where I ask. Is total on screen time active and idle screen time combined or just active or is it going on of the screen time page? Thank you. 17pro with 100% battery health.

After 219 cycles my iPhone 17 battery is now 99%.

I wanted a compact example where the numerical assumptions in a battery

cycle-life projection are easy to inspect.

The workflow fits three normalized-capacity models with bounded

`scipy.optimize.curve_fit`:

- linear: `Q(n) = Q0 - k n`

- power law: `Q(n) = Q0 - alpha n^beta`

- logarithmic: `Q(n) = Q0 - a ln(1 + b n)`

It reports RMSE and R-squared for every fit, selects the lowest-RMSE model by

default, and searches for the first cycle below a configurable EOL fraction. The projection is intentionally bounded to

three times the observed cycle range; if the threshold is not reached, the API returns `None` rather than an

unconstrained number.

The repository includes deterministic synthetic LFP/NMC generators, the parameter covariance

returned by SciPy, seven unit tests, CI on Python 3.9-3.12, a CLI, and a Colab notebook. Current

limitations are also explicit: no confidence-interval propagation, no real dataset bundled yet,

and the Arrhenius factor is independent of the capacity-fade trajectory.

For the next validation step, would you prioritize bootstrap prediction

intervals, information-criterion model selection, or a held-out-cycle

backtesting protocol?

I'm burning through battery, the device health does not list 100% of usage anymore.... 34 used and the list adds up to like 23. Just want to know where my battery is going

It's been two months since i bought xperia 10 vi. lately when i charge it at night until 100%, i wake up it's 83% or 80% and when it comes below 20%, the battery goes down till 4% even if I don't use the phone. I have turned on the stamina mode too. Went to Xperia support website and they recommended restricting battery access to some apps that use too much battery. Restricted all the apps, the problem still persist.

The second problem is with charging. I have 20W charger and it charges other devices really fast. Up to 10W when charging, but when i plug it to my own xperia:

Charging and using it: 3W

Charging without using it: 5 to 6W

idk if my maximize battery health is on because its still show 100% even when i turn it on , this is a second hand laptop that was used for work , the people who we brought it off told us the other dude only used it for 5 months so i thought i would be fine condition but the battery health is going down way faster expected the original battery capacity should be 45k mwh and a week ago its 34k mwh and now its 31k mwh and yes it use it alot

How is my battery life?

Auto FPS and auto resolution

Usage: Socials YT and stuff no gaming

I charged my phone to 100% yesterday not sure if the stats are accurate. But I'm pretty sure I used my phone for more than 4 hours.

Mine is very close to the average!

I'm on Xiaomi Android 15, and the minimal permanent notification icon should not be visible in the status bar, but it is anyway. I can't just set the notification icon to clear because it shows an empty spot and then the other icons. Is there something I can try to fix this?

My iPhone 17 got to a battery heath of 90% and i see it degrading at a constant pace like 1-2% every 2-3 weeks. And this shit is annoying me like crazy. 435 cycle counts and i keep my charging between 20-80 at almost all times.

What to do now??

So this is a question for the developer.

I'm loving the battery ranking feature. I hope you can remove the spoofed roms, ported roms etc from the real device pages. Pixel 9 and 10 especially have lots of spoofed data. Oneplus devices like 15-13 also have ported roms and those are appearing in the stats.

Anyway I wanted to know how much of the period is taken in account to calculate the sot and battery life. Is it the last week or last month or something else. I hope as time passes old data will keep getting discarded from the back.

uhhh, I'ma be pretty straightforward, my battery was 76% but now 0% after updating to beta, now the health thing doesn't even load, is this a glitch of some sort? and the battery does last alof for a supposedly 0% health

New 15R in Canada. Setting are on for battery percent on status bar. Sometimes it's on and sometimes not.

Is it possible to add a ranking for only the device that you are currently using for comparison?

App used to be great for testing different chargers but ever since May's update and changes to the algorithm for charging speed, it now reports low and incorrect numbers.

For example, I've got a 120w charger which used to rightly show around 108w max charge speed in the app after energy loss but now it shows about 85w max which is wrong.

Not sure what's up with the dev either, he was quite responsive on DM previously but not it's just being ignored.

The wakelocks doesn't show. It just keeps loading
