Hi,
I recently bought an HTC branded spare battery, I've read the initial charge just needs make the charging indicator turn green as the current is switched off by the phone then. Part way through the first charge I accidently turned it on, I shut it down stright away, will this cause a problem with the battery capacity? I've read it should be a constant charge or are battries these days much more robust?
Thanks
Neil
I would not be worried. The charging algorythms are robust.
On a related note, I have read that it is beneficial to sometimes leave the battery on charge for some hours after the LED has gone green, and then not to charge again until the battery is completely exhausted (phone stops).
I believe that this may help the battery charge algorythms to learn the true maximum capacity of your particular battery and help it run as long as possible between charges.

I have an XDa2i, after removing the battery pack earlier this week the unit now wont activate or take a charge from any source. Every time I unlock the battery whilst on charge the red charge light comes on but when the battery lock is applied the charging discontinues. Several battery changes have been tried but the unit will not charge or activate.
Any thoughts or advice on this issue most welcome as always.
Thanks
Pete
If you have got the Cradle then charge your battery itself by the mains adapter not by USB power, once the baterry charging light becomes Green, then put the battery in the XDA, lock the red button and leave it for approx 1-2 hours (or may be overnight), but do not try to switch-on the XDA, The reason behind not to switch-on the device is that the device's internal battery would be completely flattened and that would re-charge automatically once you put a main full battery to the device.
Try to switch-on the device after 2 hours by holding the power button for few seconds, and hopefully XDA should back on.
As far as I have understand the situation and if its right then you might have already lost all the setting & data stored on the device, sorry for that.
GoodLuck & let me know.

Absolutely no joy! the device was on charge overnight and the light stayed red. There was no response from the unit at all. Any other thoughts, or does this sound like complete system failure?
Any other advice would be welcome.
Come-oooon Peter I have said to charge the battery ALONE on the charger (not to put it in the device and charge), try to fully charge the battery (Just battery) on the cradle's back slot and then try the same.
GoodLuck & let me know

I have battery charge problem.
I charge (on USB) my NS about 7 hours (during I sleep), after wakeup I check charge status it was "Charged", after that I unlock and goto home screen to check battery again.It was 100% so after that I unplug charger.
The battery level was drop to 97% immediately.
Is my NS got hardware problem?
Thank you and sorry for my English.
Normal problem out it will be fixed soon

i think ive read that it helps the battery last longer.
Also, ive been experiencing some other problems with charging my phone.
When its plugged into my wall and charging, instead of increasing battery percentage as it should, it will decrease in battery percentage, really strange. I'm not sure if its the battery or my charger? Anyone else experiencing this issue?
Did XDA NS have list of problem on 2.3.2 and 2.3.3
Sorry I found that forum
That 97% is a common problem? Man... I've been trying to recalibrate my battery the whole week...
They don't need to limit the charge to 97% to make the battery last longer. They can just lower the Full Charge limit without doing this awkward 3% drop after unplugging the charger.
thank you for all answer

My understanding is that this isn't a result of a lowered full charge limit but rather the way that LiOn batteries charge: once they reach full capacity they stop charging until they reach a bottom limit (Not sure what it is on the NS but on the Evo it was 90%) at which point they begin charging again. They do this because LiOn batteries do not absorb charge past 100% but they do absorb the heat from the charge. Over time this over heating can cause issues. There is another method of charging wherein the battery charges to full and then the amount of voltage is slowed but is continued. This method is called trickle charging and awhile back on the Evo it was all the rage until reports started to trickle in of batteries smoking or even catching fire due to overheating. Hence the reason why trickle charging is not standard.
Hi everyone
My problem is.. my DS started to charge slowly.
Now it doesn't really charge slowly, If I check the voltage, I will get like 4220mv but as soon as it reaches that, the charging graph just goes flat.
If say I have charged it to 70% and it started going slow. i switch it off, place on the charger, and the lamp goes green. I turn it on, and it is showing 100%.
I have tried calibrations, diffirent kernels, wiping, factory resets e.t.c.
Another thing is that if I will run a v6 battery calibrator,it will show that actually I should have a 100% charge although a phone is showing only 70%.
So the summary: Phone charges normally when off (when recovery monitors charging), showing the correct voltage when on... But showing the wrong percentage if on charge.
Also sometimes if the battery is like 14% left. And I turn the phone off and then on again, it will show 22% bearing the same voltage as when it was 14%.
Question: Is there any way to tweak the battery indicator so it would show % values same as the v6 calibrator does it or is it a hardware fault, if yes, which part of it ?
This happens to me on my older (original) battery, but not my new one. I bought the second battery when this problem started happening. So, I think it's just a symptom of an old battery.
By the way, if you leave it on charge long enough, it will eventually jump up to 100%.
Other than this weird behaviour, it has no real impact on anything.

Thought so, mines been acting similarly lately, but strangely enough it seems to be getting better
I think I found out..
I actually purchased a new battery recently, because my old one was jumping like crazy and started discharging in a few hours..
This new battery I bought from a mobile repair shop.
It is a cheap chinese battery with no name, anyhow I just took it out to take a look at it...
And guess what, it sais 1200mah..
Can the phone be confused because of that ?
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."

Hello. I just noticed something weird on my TCL 10L phone. When the phone reaches 100%, it displays fully charged on my lockscreen. Though, unlocking the phone I see the phone is still charging. I see the battery bar being green with a charging bolt. It takes around 15-30 minutes until it says charged (and the bolt removed). Is this normal? I do not remember the phone doing this when I bought it around 5 months ago.
Changes in charging and especially sudden loss of capacity can indicate a battery failure.
Check for cover swelling/bulging, battery swelling is a failure, replace asap if so.
A failure this early is rare but Li's can fail at any time in their life.
Inspect jack and port for contamination. Use a known good charger and cable. Try cycling the battery until the phone shutdown then charge to 100%, repeat... to calibrate battery indicator.
Minimum start charging temp is 72F
Best start temperature is 82-90F
Never attempt to charge a Li below 40F
Keep battery temperature below about 101F when charging.
Do not use phone while charging as it will skew the charging curve.
Thanks for the reply. There is no battery loss. I can play games on this device, browse, and check apps and drain the battery in the same period I did since I got it. I actually charged it to 100% since went to sleep. 9 hours later the device was still at 100%. 1.5 hour of playing a game after that and the battery was down to 84%. The issue is really weird. I am thinking a battery calibration may help. I do not know.
P.S. I am currently using Android 10 and I do not want to switch to Android 11.
I wouldn't worry about it.
It's best not to charge to 100%.or below 30%.
Lu's like frequent midrange power cycling (40-65%).
As for 11, no way that crapware is getting on my phones....

Did you personally experience this on any device? This is the first time I saw something like this. According to some articles the phone may display wrong battery stats. So I was thinking calibration would be a solution to this issue.
