[Q]before starting the nand installation? - HD Mini General

sorry if the question is boring, is it important to have the battery charged above 50% before starting the installation?

I would always charge the battery to 100% when flashing windows mobile/Android roms. Why risk a battery drain during a flash, possible resulting in a bricked device?

Sounds reasonable, risk, because of impatience is not a good idea. As a new member I can not write anything there in dev treads.
For 14 hours 50 minutes I spent in standby batteries 18% ..think that it is not bad

Redirecting you to the right place.
If you have just flashed a new rom, in general, you need to go through a couple of battery cycles before the battery read can be accurate. I remember when flashing my ATT FUze I had to wait 2-3 complete charging cycles ie. discharging battery to 10% and charging back to full before I could get accurate reading. If you are experiencing worse battery time than before flashing after 2-3 cycles you might need to reflash the rom; you should see better battery time with custom roms, so I have heard.
I also wouldn't go by the battery saver timing, I would go by wpbench or real time use to get an accurate reading on battery time. I have a 1800 mah battery in my focus and it reads 24 hours on battery life
As far as i know, doesnt all the ROMs have basically the same battery life?
Ill be going out of town sometime this week and ill be out most of the day, i need a rom thatll at least last a whole 12 to 14 hours at the most or whole day at best of just occasional twittering and occasional checks on facebook and probably capture some pictures and a video and maybe an hour at most on music? im sure this phone can handle it but idk what you guys suggest
I have the same issue with ATT samsung focus with Roger latest updates, the battery meter is just not accurate, sometimes full and just reboot upon eject from the micro usb. The battery was fine until recently. Found a few other with the same issue online, no solution available yet.
*pulling out battery doesn't work*
The solution is exactly the same as it is on a laptop.
Lithium ion batteries, and, actually, come to think of it, pretty all rechargeable batteries lose capacity over time. The phone, to begin with, doesn't have a good idea of how much capacity is left, and it has to estimate based on previous performance. This is partially a result of battery manufacturers going as cheap as possible with the circuitry in lithium ion batteries.
The phone needs to figure out how old your battery is. This data is definitely lost with a new rom. Leave it to charge overnight, then unplug it and let the battery run all the way to dead. Charge it again, and your battery percentages should be correct. It may take more than one cycle, but the meter should settle into a correct estimate eventually.
Incorrect battery stats are a possible reason for fluctuations in battery life and reseting them as described in the previous post can help.
Another thing which you can do is use an app like this http://forum.xda-developers.com/showthread.php?t=1328730 to check the reported mV rating of your battery at full charge. That can serve as an indicator of the battery life you can expect with your current battery stats.

[Q] [HELP] Battery issues

Hello! I'm having serious problems with my battery. Since I installed CM10 my battery just goes from 80 to about 60 or 50%, then it drops again from 40 to 20%. Already tried to calibrate with battery calibration app, or this methods, done full wipe (did the process from the beggining, back to Cm7 and no results at all!
Pictures attached.
Please, pleaase help! I'm selling my defy, and do not want to sell it with this issue.
PS: Original battery

All you need to know: http://forum.xda-developers.com/showthread.php?t=1778492
After checking the ownership in root explorer or simular apps, recharge to 100% and let it sit for a couple of hours. Do that again after discharging it.
You will probably be selling a worn battery anyhow, but then maybe with a calibration so the percentages work. This is mostly due to changing with a fast-charger (not the stock one) or charging it not often enough. If you have the habit to let it go to 0%, then it is worn in less then a year to a degree that it last for a couple of hours less then in the beginning.
New battery is the only way, I got an anker one off amazon for £5 and have great battery life on cm10. The
above method or a change of ROM may help but the only real cure for me was a new battery

[Q] LG G2 Battery Drain Issue(s)

Hey dear forum members,
I have my G2 (D802 Europe) now for nearly 1.5 years and I've nerver really experienced that "wow"-effect everyone had with the battery life. Soon I rooted my phone and used cyanogenmod instead. It was a bit better but not for long time and now my nerves are at their end (I don't know why this has not occured earlier :?) so I went back to stock by flashing stock and unrooting but nothing helps. I want better battery life but I don't know why it is so bad.
I get about 6-8 hours of battery life with 2-4 hours of display on time with 50-70% brightness. Sometimes i have 100% brightness but i think battery life is still bad even with 100%. I only use it for calls, whatsapp, facebook, youtube and surfing. I am not even playing games on it. Anyone experiencing the same problem(s)? I was disappointed for over a year but now I have enough time to try things or even send the phone to LG for battery replacement (Root Checker is tripped. Hope it will work anyway if there is no other solution).
Here would be some screenshots of the battery life today but XDA don't want me to do that so I will describe it for you:
Time from 100% to 0% was 7 hours.
Display on time was about 3 hours with 1 hour 100% and since then auto brightness.
In the statistics the display used 39%, the OS 13%, the system 10% and the rest is below 5%
Sorry if my english is bad anywhere in the text I am trying my best.
I hope you can help me with my problem and have a nice day
Small additional info:
I am charging my phone when its about to die before I go to sleep where I would charge it normally. As Example if I use it "too much" for videos or browsing I am charging it while going on with that. And I am not the 100-4% and then full charge person. I charge it when it is possible because it drains so quick. Maybe I harmed the battery over time by doing it but it was also bad when I got the phone new so anyways.

Battery lifespan .

Hello guys ive been reading tips about battery lately but i haven't decide what is best for it. My note 4 i still have it , i charge it very very randomly , after 1year i still have 1 day of battery so i didn't do anything bad to it even if i charged it so randomly . There are alot of informations on forums that say that battery should be charged from 30-50 too 70-90 and once a month , u let it completly drain ( till the phone shuts down itself ) for recalibration . I usualy charge my s6 from 20 to 100% , but ive read that this is bad too. I don't know what to think about it and i would like some other people to tell me how they are charging it . Sorry for my english.
It's all rubbish.
It's a battery, it'll have 3 pins, a positive, a negative and a thermistor pin, that's it, there are no electronics inside the battery, it's just a simple chemical Li-Ion battery. I expect when the phone dies at 0% this isn't actually 0% at all, more a feature in software to make sure the battery doesn't get damaged. There is no such thing as 'calibration'.
Do some reading on Litherion Ion cells and you'll see just how much rubbish is scattered by people on here.
Yeah, like the old not leaving it plugged in overnight myth. I've lost count of the times I've seen that one.
To be honest with you , i don't believe everything i read about batteries and im sure im not going to drain the battery once a month just for the fun of it. Still , i am going to charge it to full every time because its easy for me to plug it in and let it sit like 2hrs and get it full than to watch over it and stop it from charging at 80% , when its green,i take itoff and that's it.
One thing to note though, which is true, is don't ever leave a flat battery flat for a long period of time as this will reduce its efficiency in the long run.
Noted. So , one more thing , what should we do , charge from 20-30 or whatever to FULL or to 80% as they say it's not OK to go full.

Well , samsung reply was satisfying . So i guess if someone would really want to care about the battery lifespan , should discharge phone ( till it shutdown itself ) and recharge from time to time (1 /month ) .
Samsung reply with :
" Regarding the charging of your device, all of the scenarios you describe shouldn't have any particular negative affect on your battery. However, completely discharging a battery from time to time can help to extend its operational life by a small amount. "
( The scenearios i described are the same as in the first post of this thread )

Guide: 8-10 hours SOT battery - restore battery health

Been reading dozen of threads on diffrent forums regarding people complaining about their poor battery health, performance, etc.
Here are my advices to obtain near 100% battery health as years passes by (I have an galaxy s3 from 2012 with 90% and an LG g3 dual sim from 2014 with 92% ???), it all has to do with user behavior:
1. Avoid not charging to at least 95% then discharging it to near 0% (example: you charge it from 0 to 50 then you go outside and discharge it to near 0)
2. Avoid high usage for more than 3 consecutive days.
3. Drain SLOWLY from 100 to 0 once a week. This drain must be done at least in 1,5 - 2 days.
4. Charge from 0 to 100 with phone off at least 1 time / week
5. Every 2 weeks Let the phone discharge in 2-3 days, with minimal use, like just calling.
6. Repeat nr. 3 as much as you can
7. Avoid putting to charge when the phone is hot.
8. Avoid charging while using the phone.
9. Avoid fast charging.
10. From 100 to 70 and from 30 to 10 go slowly.
11. Never let it discharged 5, 10, 20 % more than 1 day
12. Never charge from 20, 30 to 100.
And many more will come.
Cheers.

Well that was mostly me complaining xD
Yah these advices to prevent battery draining too much but you cant prevent it if it already happened xD
Well im barely getting around 4:30-5 hours sot without stamina mode BUT not gaming nor watching too much or heavy stuff so it sucks im gonna contact my local center to get it replaced and then ill take your advice
You don't need to replace your battery. Just follow these advices and it will recover capacity.

no i dont think so as it is physically wearing out (because I litterally tried to follow and install another guy's same apps and layout, disabled exactly same apps and ran exactly the same FW and his battery did a MUCH better job).
Dude, it's all about battery CAPACITY! You can restore it if you let the battery recover following my guide.
Batteries tend to loose capacity if abused, but also to recover the capacity. Remember that it does not have 1 year. There are batteries with 3 or 4 years usage and doing fine job.
If you follow my guide you will notice an increase în capacity after 1 week.

I dont understand, isnt the capacity some thing physical? I mean how can a battery be bad and then recover like its new?...

This advice about draining and charging seems to be similar to advice that used to make the rounds suggesting you should calibrate your battery. Actual calibrating of a battery isn't possible (and advice like this guy's was debunked long ago), but sometimes your OS will give you faulty readings. You could take a look at https://forum.xda-developers.com/android/general/guide-how-to-callibrate-battery-device-t3308554 to see if there's anything useful.
Beyond that, generic tips like https://www.androidpit.com/how-to-save-battery-life may be helpful. Or, you may just have a bad unit. It happens.
This is a quiet forum so you probably aren't going to get far posting multiple questions about whether your battery is any good. If you think it's way off normal, then perhaps you have a warranty issue, or maybe you have a local shop that does battery surgery with OEM units. Being that this is a sealed full glass body, I doubt anyone could replace the battery.

So, despite the fact that a lithium battery can't change capacity, and everyone from Google to good developers saying you can't change your battery's capacity, you're suggesting he can? You might be able to get the system to more accurately display the stats by following some full charge and discharge guidelines, but the suggestions you're making don't change battery capacity because they can't.
And yes, batteries most certainly do lose their ability to hold a charge over time, which is different than capacity.
