There are lots of myths regarding lithium batteries.. some say you are not supposed to overcharge it (charge it only when it's running out)
Some say it doesn't matter since lithium can be recharged as much as you want and it won't deteroriate the battery's life.
Which one? Can I recharge my Touch Pro 2 every night before I go to bed and leave it until morning? or should I do it when it's running out to preserve the battery's life?
You should keep the device on A/C power as much as possible. So, it's fine to charge daily overnight. Every once in a while, you should let the battery run all the way out before recharging. What this will do is keep your battery meter reading accurate. If you don't do this, eventually, your device will "think" it has more juice than it actually does.

Ah thanks
So to cut the story short, recharge it as much as you can and prevent the battery ever from being run out
Nahhh, not fully true. Somewhere else on the site of batteryuniversity it sais that completely discharging the battery will reset it's memmory. This is usefull after a lot of charges and discharges (in the beginning, I think they already did this (you may hope).
(the memmory helps the battery know where his power is storaged and how much power the battery has left. But doing this frequent speeds up the battery 's lenght of life
In my experience
Enjoy your device and charge battery when needed/desired
Use it normal
Batteries have a duration of 3-4 years aprox, no matter if you charge it every night or leave it till it´s empty...
When battery fails you buy another one and so on
Just my opinion,
My experience with the battery life on my touch pro 2 is that I will keep the phone usually docked in my cradle on my desk when working so it's always on charge. When I use my battery I wait till it's about 40-30% drained and will stick it on the cradle again.
When I'm in my bed ready to sleep, I use the normal charger and leave it on charge over night.
Still experimenting though.

Do you have a cradle for your Rhodium ? Where did you get it ?
Check my battery thread, it will tell you pretty much everything about li-ion batteries and taking care of them

Hmm, first of all Li-ion batteries have NO MEMORY unlike NiCd batteries. You probably refer to resetting the reading gauge - which is related to device's capability of getting accurate reading rather than battery itself. It is recommended to let the device die once a month and give it a full charge to "recalibrate" phone's battery meter (not the battery).
But you should avoid hitting 100% battery mark as well as going bellow 30% as much as possible.
from my experience as a phone shop owner and owner of many many phones i always advise my customers and friends as follows:
1st charge 10-12 hrs. allow battery to fully discharge
2nd charge at least 8 hrs
after 2nd charge you can charge and use as you want. the initial 2 charges kick start everything and starts your battery cycle on good stead
never had any complaints!
Another thing, is it bad to use your device whilst plugged in?

The battery should be as cold as possible when charged. So if you are using the phone the battery power drains and is charged at the same time. Therefore it gets warmer than without.
Best for the battery is to be charged when the device is switched off completely.
I wouldn't consider that much of a problem, because you have bought the device to use it and not to live in fear that you treat the battery right
when plugged into USB and playing a game on my TP2 I got the message the device is using too much power, and it drained the battery even though recharging via USB. No problems when using AC adapter though.
Used my XDA Orbit 2 for 2 years now, and mostly charged at free will. Battery is still fine, so no special charging rules for me...
I noticed though, that charging over USB takes quite some time while charging over AC cable is done within an hour or so. When looking at my AC it has 5 Watts of output power, while the USB only has 2.5. That would explain your issue with the battery running out even when having the USB cable plugged in.

How long does it take to fully charge your One-X?
Mine is already charging 3.5h to get from 40%to 80%....
Using the default charger, and not using the device.
Isn't that a bit to long?? My HD2 was completely charged in 2h..

I am no expert, so don't hold me on this one, but I believe your device charge should speed up due to firmware updates and also once the battery has been 'worn' in - just stuff I have seen about.
Can anyone else provide me their charge times? How long it takes to charge from A to B?
Pls mention with wall outlet or USB.
I've noticed this as well. My Arc charges in like 2-3h to full. the One X takes about 2 hours to get to about 60% from 30% (using USB).
edit: wall charging takes just as long.

Interesting reading about lithium based batteries
this is a quote from batteryuniversity dot com
Simple Guidelines for Charging Lithium-based Batteries
• A portable device should be turned off while charging. This allows the battery to reach the threshold voltage unhindered and reflects the correct saturation current responsible to terminate the charge. A parasitic load confuses the charger.
• Charge at a moderate temperature. Do not charge below freezing.
• Lithium-ion does not need to be fully charged; a partial charge is better.
• Chargers use different methods for “ready” indication. The light signal may not always indicate a full charge.
• Discontinue using charger and/or battery if the battery gets excessively warm.
• Before prolonged storage, apply some charge to bring the pack to about half charge.
• Over-discharged batteries can be “boosted” to life again. Discard pack if the voltage does not rise to a normal level within a minute while on boost.

And I also read that charge time should be almost 3h for a full charge(i suppose this is when device turned off). You could get about 70% charge in about an hour if I remember correctly.
Hmm not gonna turn off the phone for every charge tbh...
Sent from my HTC One X using xda premium
While charging and using the phone it takes around 5 hours to get from 5% to 14% when not using but charging takes around 3-5 hours to charge from 25% to 100%
My second charge, from 0% to 100%, with device shut down took 3.5 hours to show the green led... quite a long time since I was using the wall-charger... I hope it will improve with the fw update and after the battery has been "initialized"
Today I began charging my HOX at 1:44 (1%) and it finally reached 100% at 4:59.
I was using HTC's charger.

same here, about 3h from shutdown with 0% to seeing green LED
using wall charger
Took me three hours with original HTC wall charger and original HTC cable (no extension) to charge from 4% to 100%. Terribly slow!
EDIT 1 : Apparently BWM doesn't show accurate power draw while idle on the One X for now, so my post has become totally irrelevant
I always install Battery Monitor Widget on all my Android devices and monitor charge and discharge constantly.
On my Desire Z, if it's below 70%+ I get a charge rate of about 750mAh from wall socket.
But on my One X, with the same charger (both are rated for 1amp, and both HTC), my charge rate drops to 450+ at 60% battery life.
It's probably a software issue, but charging the One X does take noticeably longer.
I don't think it is a software issue, as the battery pack is larger than before. Also when you are active the phone itself draws large amount of current and it definitely slow down your charge rate.

When your phone is idle with screen of, it shouldn't drain large amounts of power while charging. Can't imagine that has a huge influence on charge times tbh.
And for capacity, my HD2 was charged in about 2H for a 1200Ah battery, this 1800Ah One-X batt should be full in like 3h... not 5 or 6h...
The official wall charger took 2.5 hours to fully recharge the One X
Ok after an amount of charges, it now takes only 2.5h - 3h anymore for a complete recharge.
Official wall charger.
Did a charge on mine this morning from dead, took 2.5 hours to get to about 90%, left it for another hour but it didn't go up the last 10% stayed on 90 even after the extra hour. Off the wall

I'm thinking the same... I don't mind turning it off on a night for the first 2/3 charges but personally this is my only phone (don't have a house phone) so will be keeping it on through the night in case someone needs me in an emergency etc...
Was interesting to read that batteries prefer a partial charge and do not need to be fully charged; which is good actually as mines got around 18% left and I'm about to stick it on charge for the next 8 hours.
Had a Nexus 4 and I did the overnight charge,
Is it the same for the 5X with the rapid charge?
Thanks
Gary
There is not a better way to do it, you can rapid-charge it overnight, during the day, in you car, every 3 minutes with 10 minute pause or whenever you would like to.
For me, I use a normal charger overnight and the rapid charger when I need juice during the day or in the car, or when i forget to plug it overnight.
I remember reading on a reputable tech site about how lithium works, you can leave it overnight with no issues but they have a specific amount of charges in them. E.g. 500 charges for a battery and a charge will be counted anytime it goes above 80% etc. After 500 times, your battery should start to see degradation.
All the above figures are made up but that was the gist of the article i read, so don't worry about leaving your phone plugged in, the os will automatically limit the charge once it reaches 100%.

Google's take on the subject:
Battery lifespan, charging & usage tips
Good charging practices and care can increase your battery's lifespan. Use the tips below to keep your battery healthy.
6 battery charging & care tips
1. Use the power adapter and charger that came with your device
Other chargers can charge slowly, not at all, or damage your device or battery.
2. Keep it cool
Avoid situations where your device can overheat. Your battery will drain much faster when it's hot, even if you're not using it, and this can even damage your battery. Keep in mind that your device warms up when it's plugged in, so try not to keep it charging all the time.
3. Don't worry about calibrating the battery
You don't need to teach your device how much capacity the battery has by going from totally charged to completely drained.
4. Keep it more than half charged
For the best battery lifespan, try to keep your battery charged above 50% as much as possible.
5. Try to charge a little at a time
Small charges throughout the day are best for battery health. Battery lifespan can suffer if it's charged from zero to full and then completely drained on a regular basis.
6. Store your device half charged
Leave the device with a half-full battery if it needs to be stored for a long time.

I just bought a lenovo p2 after hearing some impressive review pf its battery.But my phone discharged 25% in 4 hours.My 3g connection was on,I played coc,played some music.Is it a battery problem or is it normal?
Your battery will take several cycles to achieve full capacity... let it run down, then slow charge it (NOT with the fast charger supplied) and see how it goes... you should see 2 days of use, although videos and music etc will negate that.

The only thing I disagree is to use a different charger. The supplied charger will automatically switch b/w QC and normal charging (it's not entirely related to the charger either, with processor having some role in it)
Quick charging creates heat in the cells... the worst thing you can do to a battery ! Far better to slow charge, which is more likely to achieve maximum capacity.
Once the battery is "conditioned" then yes - use the fast charger, but the same laws of physics apply... the battery life will be reduced overall, but its a trade off against convenience, and how long you personally plan to keep the phone.
-If you lost 75% of charge in 4 hours that is too much... probably because there was a bad first estimation of the level of charge?
-If you lost 25% battery in 4 hours of intensive use (so you still have 75%) that sounds ok to me.
Also I dont use the fast charger, because battery gets a bit warm if you use it, although that is normal, excesive heat could deteriorate the battery in the long run.
Guys i think the problem is solved.The first 50% charge drains in say 6 hour but the rest 50% lasts like9-10 hours.
Hi all,
occasionally I see my 7 months old Pixel 3a XL can't hold battery power from 11% down. Switches off very fast, abnormally fast. Then if I power it and start it then keeps on restarting until battery level is higher than 5-6%
I use the original charger only. Sometimes it appears, some it does not and I can see it discharges as expected.
I try to keep my battery within 40-100% full and discharge it very rarely to 0%.
Anyone facing those abnormalities? Can't think of connected events - updates, etc ....
Cheers
p.s. after last night happening again, charged the phone from 0% to 86% (phone was off during charge), turned on on 86% and left over night on the shelf. Usually drains 2-3%, this morning it dropped from 86% to 62%. All connections off, nothing unusual shown in the battery usage stats...

That's pretty weird
My 3a xl (about the same age as yours) doesn't use more than 10% max when left overnight. Are you using AOD or anything?
Sent from my Pixel 3a XL using XDA Labs
@Skittles9823 nothing beside stock Android and apps that I've used forever. Strange is that it's occasional - also occassional is initial drain from 100% to 92%.
Maybe its time to flash it - nothing suspicious is shown in batt stats
I use the fast charger that came with it. Not sure how it affects battery life long term. I try to keep it 100% to 40% usually and not charge it if not necessary..

I think popular wisdom is that both fast charging and in particular charging to 100% are not kind to the battery's longivety. Divided opinion about the effect of discharging to low percentages. Personally I charge to between 70 and 80% unless I know I'm going to need more capacity. 3a XL has a bigish battery, which helps. I recharge most nights but only to 70-80%. End of day I usually end up between high 40's and low 30's charge.
I manually set all apps I don't actually need to run in background to 'restricted' background use.
I charge mine up to a 100% often, when using it heavy.. I never heard of charging a battery to 100% being bad for it, unless you believe everything that is told or should I say sold to you.. Sounds like a faulty battery. If still under the 1 yr usual warranty I would have it replaced. I have drained mine down to less than 20% and still never experience any issue that OP state.

It's actually true. Lithium Ion batters degrade over time, the speed of which, depends on the amount of battery cycles they go through (0-100% and vice versa). Others have done the research and the math and found that generally a 20% to 80% and vice versa charge seems to be the best for longevity.
Personally I charge to 100 but try to charge my phone when it gets to 20-30%.

So very true my phone my money. In all my years of using cell phones, I think I have actually replaced a battery once because it went bad.
Thank you all for the links and the inputs!
One more symptom - when is very low like this morning - 1% and put it in charger - phone shuts off.
I will keep the battery in 40-80% for the future and limit the drain below 40%. I tried to charge it slow with USB - took me like 6-7 hours...
How long it takes you from zero to 100% with the stock charger - looks very fast to me - 0% to 67% in 35 mins
I personally tried to research and could not find what is worse for these batteries - number of cycles (obvious less when used below 40%) or the low capacity usage ?

The included charger is a fast charger, good for headlining how fast it charges, not so great for the battery. I just use a 'standard' (Anker) USB charger.
Jury's out on if deeper discharge is bad, but it's the number of complete cycles (0-100% counting as 1). So 40 - 80% is 0.4 of a full cycle, and you're not stressing the battery so much by taking it to 100%. Many folk here replace their phones frequently enough not to be bothered by all this - if they sell it when 20% of the battery capacity's gone, that's fine.
I've observed the behaviour and few things made me question myself...one time I can see 13% battery and palying Youtube just shutdown the phone. Put it into charger and started showing 4% as initial charge.
There was another time when using Viber video shutdown in 23% but can be overheat or software bug.
I try to keep it these days above 40% charge but still use the supplied charger till I buy new slower one.

The good news is that this phone seems to be pretty easy to repair and a battery replacement could very well be a good option for you, especially since you wouldn't be compromising any water resistance or anything
