Can I recharge the battery every day?

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.

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.

Battery charging BUG

Hi every one,
As far i know, there is a BUG on every official ROM for European GSM Touch Pro2.
When your battery get full charged and keeping it plugged to the wallcharger, then your Pro2 start taking the power from your battery and NOT from the charger.
This can be checked by yourself and you will see that even with it connected, the battery in running down charge, till you unplug it and plug it again after some minutes/seconds.

Yeah, I have noticed it as well. Anyone have a solution?

Not a bug. LiPoly's do not like being trickle charged, therefore the charger turns off.
I have not verified it on the TP2 but I suspect that if you let it sit long enough the battery level would drop to some level and the charger would charge it back to 100%.

This is a rather good new if it can manage battery loads cycles...

No it is NOT doing that, so to me it is a BUG.

just thought i would add this
for some reason on saturday i charged my phone via usb/pc and it lasted less than 24 hrs
so on sunday i drained it and charged it vis the plug
its still going noe
72 hrs 23 mins in stanby 30 mins talk and 4 hrs 7 mins use since 17.43 on 18/10/09
is never been this good so i thought it may be the new rom

Lithium-ion
(Li-ion)
Do charge the battery often. The battery lasts longer with partial rather than full discharges.
Do not use if pack gets hot during charge. Check also charger.
Charge methods: Constant voltage to 4.20V/cell (typical). No trickle-charge when full. Li-ion may remain in the charger (no memory). Battery must remain cool. No fast-charge possible.
Rapid charge = 3h
also i have read some where on xda that once it reaches 100% it'll stop charging

My Kaiser will. It turns off when you pull the battery, but you can turn it right back on.

Every one is talking about battery and it's components but no one speaks about that with charger pluged in, it should supply power and by pass the battery once it is fully charged like others models do.

sounds like you all need to do warranty exchanges for that lol

i hope this helps

Have in mind that once the battery is fully charged, it never go to charge again till you unplug the cable of your wall/car charger... so what will hapen then???

hello anyone know about the issue with the battery ok when i charge my euro tp2 all night and when i go to start>settings>all settings>system>power i then click on the infomation tab and under last full charge i get "not applicable" and get 0 hours and 0minute for the rest
im running the offical htc 6.5 rom

To me this sounds CRAZY. So people are saying that when the device is fully charged it starts to use its battery, thats just crazy... So basically charging it overnight leaves you with "almost" full battery in the morning...
I havent noticed anything out of the ordinary, and every morning when I come and take my device from the charger the charging light is green (opposed to the orange when started charging) and the battery shows to be 100% full.
I will check this again in the morning as I havent really paid 10000% attention to it, but I think I would have noticed the weird behaviour…

noticed this since day 1. my dash didnt do this. i did notice that a soft reset will resume the charge.

This is normal behavior for battery powered devices.
When it's plugged in, the charge circuit charges the battery.
The device itself always runs off the battery when it's available, this is why some devices won't power on without the battery installed, and many devices won't power on with a failed battery installed.
Laptops do the same thing, though they can switch to AC only without losing their state.
It's a holdover I think from when electronics couldn't switch between power sources fast enough to not lose anything (I remember the original game boy would reset no matter what if you tried to switch between batt and AC). It's possible that cell phones can't make this transition since there isn't really extra space to stuff in the bits that allow this (some large-ish caps).
I've also heard that this reduces wear on the electronics, because the voltage is more reliable, but I've never seen that documented.

I don't think this is true for (modern) laptops. All the macbooks and thinkpads that I've owned had a feature that if you plug it in while the battery is above X% (usually around 96) it will not charge. It even gives a message saying "Not Charging" in the battery status. The battery percentage then stays constant no matter how long I use the laptop, so it is not DIScharging either. Therefore it must be running from AC. If it can do that, I doubt they would have it run off the battery as soon as it is charged to 100% on a full charge cycle. I think any time AC is plugged in, a modern laptop will run from AC rather than battery, regardless of whether it is currently charging the battery. However, that's just my theory from personal observations.

The Best To Charge Battery?

Hi All, I have question. Which one better to charge
1. Wait until Battery level reach 15% or less
2. Charge it every we want it, example battery status in 40% because we want to travelling, we charge it until 100%
3. Charge it every morning
4. Other Tips?

Hello
You should just plug it in when ever you have the chance m8.
Li-ion and lipo batteries does not suffer from the memory effect as nicd and nimh batteries did.
The li-ion and lipo batteries will most likely die if you do a full discharge, but no worries, when your phone tells you that it's out of power, it's not fully discharged.
Your phone has at built in protection, that shuts down the phone before it uses all the power on the battery.
(Have been working with batterie for many years, as I have been flying eletric model airplanes, with all types of batteries)

There are a huge number of threads on this!

Just keep it turned on m8.

leaving it on has a disadvantage
as soon as battery is full, it discharges. at a certain point it would charge again.
you lose unneccessary charging cycles for your battery. so charge over night with turned off handset.

Not true really. The life of Li-ion batteries is mainly rated in full charge/discharge cycles between what the manufacturer recommends as the limits. Fox max life this is often a maximum of 80%SOC and min of 20%. They ship them about 40% SOC as this is where they have longest shelf life. The phone manages these limits for you so you don't need to worry. The best thing to do is to keep it topped up but let it run down enough during the day, or it reduces battery life (think laptop that gets left plugged in Vs one that gets discharged a bit per day - leaving it plugged in kills the battery).
IMHO - Use it until your next at a charger be that at 70% or 7%.
JAmes.

This thread here might be a good reference for this topic.

1. I always try to charge it 10-15%
2. Sometimes i do charge it if the battery is 40% and im worried it might not last because i go somwhere, so charge it till full and unplug
3. Most of the time i charge it over night having the phone on.
Right now, end of day 2 and battery level is at 29%, probably due to 3g turned off as got connection failed error for couple days and cant connect :<

Put my new second battery to charge last night around 9pm - turned Desire off. The green light came after midnight, but I let the charger stay on. I disconnected the cable around 9am this morning - and the phone was on!!
It looks the phone turns on automatically when its fully charged(???!!!)
The charge was 94% with the green light on. Makes me doubt if the suggested (see other threads) initial charge needs to be 12hours. :/

[Q] Charge times

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.

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.

Battery hold from 11% to 0%

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...

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
