Hi, recently my phone stuck at 90% battery level... The charging is turbo charge but the value never goes more than 90% even after 2 hours charging it will remain at 90....I've rebooted several time... What more weird is that I've turned off phone at 90% battery level and keep it charging for about 30 minutes the battery level drop to 85%.....anybody have recommendation what to do except changing the charger as the charger is ok when charge other phone.

For the past day the battery on the tablet seems to be stuck at 97%. If I plug the charger into it while in standby its says 'charged' but when I unlock it and check the battery percentage it says 97%.
I got the keyboard dock about 2 days ago and when the keyboard and tablet were paired the battery status would just be charging (lightning). Now it's just stuck on the same number. I had some notifications this morning for a firmware upgrade (tablet and keyboard) so I installed those but theirs been no change.
Any idea's ?
If it's any consolation mine's stuck at 96%. I'm guessing it needs to discharge fully and then be charged to calibrate.
yeah..agree this is probably just a calibration issue...it's ok..
Infinite Battery FTW.
Don't know if this is related. But I noticed that until my battery level goes down to 95%, it won't charge back to 100%, when it reads 96% and above even if its plugged in.
Considering how easy it is to boom a Lithium Ion battery I wouldn't be surprised if they decided to be conservative with it. 4% of 16 (potential) hours of use isn't too earth shattering. It does tweak the OCD though!
You would rather have your battery sit at 96% instead of it not being able to take a charge after 8 months..
Is the first charge on the Nexus 5 still as important as a few years ago? Or is the N5's Li-Ion battery not as sensitive as Li-Po batteries?
I always used to plug in a new before booting them up, charge the battery completely and then unplug it. When the charge went down to about 5%, I plugged it back in. I always did that two or three times and then - while still trying to do it like that all the time - allowed myself to charge the device for a few minutes only when it was necessary instead of plugging it in and leaving it at home.
Well, on the N5, I didn't manage that - I actually forgot to monitor the battery level yesterday evening before going to bed. This morning, I noticed that the battery had reached 1% during the night and the N5 shut itself down.
Of course, I did now plug it back in, but I wonder if I could have damaged the battery by letting it run down to 1% on the first charging cycle? Or doesn't this matter at all and it will still reach its full capacity after a few charging cycles?
Thanks

I wouldn't worry about it, running a battery to empty is indeed bad but they don't allow you to run it to empty. It is programmed to show 1% and shut down before the battery itself is at 1% to prevent you from damaging it.
Use your phone, when charge is about 20% connect your charger and do not disconect until reaches the 100%.
This is what i have done with mine.
I have reached 2 days standby with about 3 hrs of screen on time.
What voltage ranges do you guys get for 100% and 1%?
I bought a new EB40 for a friend's phone and am getting some weird effects. I've previously done the EB40 in Atrix HD in my own phone and it's been fine, but I haven't actually let it run down below 50% yet.
Full Story:
At first the phone wouldn't turn on, but the LED would turn on when I plugged it into the charger. I left it on the charger for 10 minutes and then it would turn on to the battery charging screen, reporting 1% battery left.
I then made it boot into the OS. After a couple minutes charging, it jumped to 100%. I left it on for an hour, then disconnected it, and then it was slowly going down like normal. However, after it hit 85% or so, it just suddenly died.
Then I had to charge it and it was back to 1% and the same thing repeated.
I tried clearing battery stats (/data/system/batterystats.bin) but it seemed similar. Now I'm trying to run the battery till it dies, it's been at 1% for quite a while. Then I'll charge it back to 100%, but is it possible I got a dud?
We ran it down to 1% again, it died, and and it went back up to 100% again. I'm figuring once I get down to the real 1% and dies, when I turn it on it won't be at 100% like every other time. Then perhaps it will charge all the way up to the real 100%.
So far it's been like this voltage wise:
3.966V: 3%
...
3.725V: 1%
died
3.696V: 100%
...
3.663V: 1%
died
3.661V: 100%

i believe when these batterys are fully charged it should be around 4.300 so if the most your getting up to is 3.700 there is probably something wrong
I have noticed that when i plug my Z5 in to charge overnight, it will charge to full in just a few hours and then remain plugged in for the next ~6 hours until i unplug the phone 'fully charged" in the morning.
My theory is that the phone loses charge (maybe to protect the battery?) when left plugged in at full charge.
I will only get 3 hours SOT max if i leave my phone charging overnight. But if i unplug my Z5 as soon as it is fully charged i get 5 + hours SOT.
Also, often when i plug my phone into charge at 1 or 2 %, it sometimes actually causes my battery to die, before the phone boots again and starts to charge. Does anyone else notice this?
I am using the stock sony UCH 20 charger with came with my Z5.
What do you guys think?
That does sound peculiar. It should be noted that while it is normal for the phone to protect the battery by cycling between 90% and 100% when plugged in (battery gauge doesn't account for this, that's why it appears full all the time), it definitely shouldn't cause a 40% difference in SOT even if you happened to unplug when the battery is at 90 percent.
Yes, you're right. Once the battery is charged to 100%, the phone stops charging and will let the battery drop to around 92% and once it hits 92% it will start charging again to 100%. Even if you unplug the phone when it's showing 100% after charging at night, it might actually be charged to 93% for example. That's why very often people complain that the first 10% of the battery drops very quickly, while in fact it's just the battery meter catching up with the battery charge. This is done to protect the battery and ensure it retains charge after many cycles.
Regardless of that, the difference should not be that huge. For me it's usually extra 30 minutes SOT.
It seems the stock firmware has a load of random wakelocks but I have hope that a soon to come update will fix most of the issues, if you are rooted I suggest that you use greenify or amplify (reqires xposed)
I spend a lot of the day with my phone tethered acting as a hotspot with unmetered data for my laptop, so the battery would drain very quickly if the phone was not plugged in. But at the same time, this means that I'm constantly plugged in and maintaining my battery at 100%, or if I return after a meeting or lunch, I'd be constantly charging from 80% back to 100%. I understand that both practices (keeping the battery at 100% and charging the last 20%) are not good for the battery. Since I usually have access to a charger, I don't really need to be charged to maximum battery capacity most of the time.
Is there any way to get the Pixel 2 XL to stop charging beyond 80% ?
Searches led me to https://android.gadgethacks.com/how...oid-device-avoid-excess-battery-wear-0176280/ That tells me to set /sys/class/power_supply/battery/charging_enabled to 0 to see if it charging stops.
But my Pixel 2 doesn't have /sys/class/power_supply/battery/charging_enabled. It has /sys/class/power_supply/battery/charge_disable instead, but setting this to 1 does not seem to stop charging. So it seems unlikely that Battery Charge Limit.apk would work. Does it work for anyone else?
This is wrong lithium-ion batteries are designed to be topped off, they last the longest staying above 30%.
My understanding is that these are not good for battery lifespan:
- charging the top 20%. I.e. charging from 80-100% uses up more charge cycles than 40-60%
- keeping the battery constantly at 100%. I.e. storing at 50% is better than storing at 100%
Are these inaccurate?
And, is there a way to limit charging to xx %?
Battery Charge Limit is closest to what what you're looking for - here's the main post.
https://forum.xda-developers.com/android/apps-games/root-battery-charge-limit-t3557002
When should you charge your phone?
"Leaving your phone on the charger all night (or all day) is far better for your*battery*than running it down and charging it up. 2.*Charge*a little bit whenever you can. Lithium-ion*batteries*don't respond well to being*charged*all the way up and then run all the way down."
