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!

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.

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...

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

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.

Alright, I picked up this setup a few months ago and I really enjoy the battery and the charger.. Well, I really don't like taking the battery out every day. So, my question is why does the phone stop charging at a certain point? Maybe I am not understanding when to clean the battery stats..
When the battery charges off the wall charger, it last way longer.. But when it charges over night through the phone, it doesn't last worth of a crap..
Can there be a change somewhere in the code, to let the battery charge longer?
your thinking of a sbc kernel or "trickle charging" by using one of these kernels you'll get what your aiming for although there are many reports of batterys frying or even melting. Ive never experienced any problems before though.
There are a number of available kernels that 'hack' the method by which the device charges. Use at your own risk, as there are potential implications for the life (and stability) of the battery.

So does the wall charger trickle charge the battery like the hacked kernels?
Will the wall charger damage the battery like the hacked battery kernels, or does the wall charger have intelligence enough not to overcharge it?
There are countless different external chargers on the market, so there's no 100% accurate answer to that. Most external chargers are applying a safe charge in a similar manner as if you charged the phone directly while it was turned off. I don't know specifically of a dangerously designed charger out there, but I'm simply acknowledging that one could possibly be out there.
In the specific case of the linked product above on Amazon, the product description says,

In fact, it says that is using a charge current of 350mA on the battery. That's very gentle, but also why a number of the reviews say that it takes longer to charge with it than charging the phone directly.

The wall charger is set to stop at a certain point. To all I know it doesn't overcharge. I know my battery lasts longer.

Sounds like a similar or identical charge when you turn off your phone and just plug it in.
It charges it more but will also shorten your battery life in the long run, though I'd assume it wouldn't be very dramatic. If you kept tabs on it you'd probably notice a significant difference in a couple months on which battery holds a charge better (phone on charged vs charger charged)
I found a good combination for me was to get the HTC extended battery and use a Kernel that is less power hungry (such as chad's incredikernel).
With a silicone case around the extended battery, it really is a nice setup.
But whatever works for you, the battery swapping would drive me insane though.
Is it normal if note 2 cost you 5-6 hours to full recharge 5-100%? it's ~3 hours before. And after 5 months it take too long for recharging.
Im used Alliance v3.1 - perseus kernel 3.0.36. Wifi on all the time. 3G not often. Note2 sleep when recharging (untouched).
If you still use the original cable, try to change to different cable. Check your voltage using galaxy charging current (root).

How old is your battery? When I mean "old", I mean how many full charge/discharge cycles has it been through? Do you let your battery go below 5% often? Is it an original Samsung battery?
As batteries get older, they may take a longer time to reach full charge. However, to truly troubleshoot the cause of the problem you need to:
a) have at least another cable to compare with
b) Measure the current that the device is getting during the recharge. There is software that can give you this info.
Without these questions answered and these two tools, it will be difficult to accurately troubleshoot the cause of your problem. Once you are able to provide some more info, we'll be glad to help you.

OK. Lets start troubleshooting your problem but first some basics to help you better understand the issue and maintain your battery in good shape and maximize its longevity:
Full battery discharges - until power shutdown (0%) - or discharges that drain the battery below 3% must be avoided because they stress the battery and cause premature wear. It is better to perform partial discharges and frequent charges instead of performing a full discharge followed by a full charge. I never let my battery drop below 5%.
A discharge/charge cycle consist of using all of the battery charge (100%) but not necessarily at once. For example, you can use half its capacity then fully charge it. This is not a discharge cycle, it is only half of a cycle. Only if you do this twice does it counts as a single discharge cycle (50%+50% = 100%). Same goes if you use 30% then charge, then use 20% then charge, then use 25% then charge, then use another 25% then charge. You charged 4 times but you only did one cycle (30%+20%+25%+25%=100%). So it may take several charges/discharges until a full discharge cycle is completed.
Charging speed depends on the amount of current the battery is fed. The Note 2 can be charged with a max. current of 2A (2 Amps) or 2000 mA (2000 milliamps). If you check the stock charger's specifications, you'll see that it's output is 2A. However, not all USB cables can conduct this amount of current. So, even if the charger is outputting 2A the battery may be being fed less because the cable can't handle 2A. Hence, the importance of the cable. One way to check this, is by installing a software that can read the amount of current that is being fed to the device. I personally use "Galaxy Charging". It is free and serves its purpose.
Also, charging speed is not linear. You probably have noticed that when you charge a totally drained battery, the first 20% are charged pretty quickly and the last 10% are rather slow.
Last, if you charge your device through a regular USB port from your computer or another device, it is perfectly normal that it charges much slower since the original USB specification defines an output current of 0,5A. Even the so-called "charging ports" from today's laptop don't output 2A (not any that I know, at least). The fact is that even most wall USB chargers don't output 2A and even some of the ones that claim they do, actually don't.
If you are having trouble understanding any of these theoretical facts about charging, please let me know and I'll try to explain them better. I don't know if I got through to you.
So, let's see what is wrong.
1) Download "Galaxy Charging" from the Play Store. There may be other, but it seems this one is popular among XDA members, so it is easier to compare figures.
2) Take the cable with which you are charging now, the stock cable and another USB cable.
3) Make sure the battery is more than 20% charged and less than 80%.
4) Shut down all apps, including the ones that are running in the background. Take note of the initial battery level (%). Charge the battery using your regular cable. Run "Galaxy Charging", check the "Now" input current and take note of it. Let it charge for a while (no need to fully charge it). If you want to, you can also take note of the charging time. DON'T USE YOUR PHONE while charging!!! If you do, you won't be able to truly compare the measurements.
5) Take note of the "Maximum", "Now" and "Avg" figures in "Galaxy Charging", unplug the charger and take note of the final battery level (%).
6) Use you cellphone until the battery level drops to the initial battery level at the begging of the charging procedure. Repeat steps 4) and 5) with the other cables, not forgetting to take notes of the currents measured by the software.
This may sound like a pain in the a$$ but unless a procedure is repeatable, you cannot draw any serious conclusions. The initial and final battery levels must be the same because, as I said, charging is not linear. So, the range at which this experiment is conducted must also be the same. Also, charging times can be affected by variables like: battery age, room temperature, mains current variations, how low the battery level is and so on. So, other people's charging times are a rough guideline only. Not to mention the people who use their phones while charging or keep a zillion apps running in the background and them post their times on the forums like if they meant something.
Let me know your findings. I'm sure you will find something of interest if you take the time and trouble to follow these steps and maybe we can all learn something in the process. Good luck.

Interesting findings. It can also be a bad contact between the cable's plug and the phone's USB port. I had a problem once with a cable and found out that the problem was the metal end of the USB plug itself that wasn't making appropriate contact with the USB port. A small pliers and a bit of pressure on the right spot solved the problem.

Hello.
Would you help me to resolve this problem:-
I've just got new update for my Note 2 N7100 today (31.12.2013 as at my local time) with the Omni ROM Kit Kat 4.4.2 and flashed it successfully. The problem is that since I did customize my Note 2 with the said ROM, I could see the battery drained a bit faster even Kit Kat used less RAM on certain running apps (as I believe this would help me conserving more battery life) and since the latest update, I found that the recharging time took a longer time to even reach 50%, if compared with before rooting with the said ROM (real scenario: recharging battery as usual via original recharger, but after almost 2 hours (started at about 7.00 pm till about 9.00 pm), the battery itself just clocking not even 40% recharged). No idea what is the real problem, could be so technical to me as I could not by myself figure out what happened, even though looks like the ROM works okay and stable to my Note 2.
So, any advice?
TQ!
Hello!
Charging problems started to occur a month ago on my phone. The problem is that it charges really slowly, but other times normally.
I experienced that if I plug in the phone when the battery is between 20-60% it charges super slowly.
Sometimes it speeds up but more often not.
Here are some screenshots that show that sometimes it takes like 6 hours to charge and sometimes it basically just hovers around a percentage and doesnt do anything. Gets like 10% overnight.
On the second picture you can see that it charges normally till it reaches 55% then it slows down to like 5%/hour speed.
I noticed this while the phone was draining battery even tho it was plugged in while using it.
I bought a new OEM battery and its the same with it aswell. Some chargers charge it quicker, some slower, but the problem occurs with every charger.
What do you guys recommend me to do?
Thanks a lot!
is your charger 2 Ampere as it should be?
U can also try to recalibrate the battery deleting the data/system/batterystats.bin file

Thanks for the reply!
I have used many chargers since I have this problem, but mostly the one that came in the box.
Ill try deleting that file if its possible withouth root.
Edit: It seems i need root for it, so its not an option for me.

Actually brother initially same problem occured with me and it was persisting on the same way load since i come to change my charger now before i was charging it with blackberry passport charger it was really cool and even charges it faster that i mean around 50% faster than the previous charger, but now days m befitted with moto g4+ which meets to charge my lg g3 around 65% faster
But brother dont use any local company pr anypther charger as it may damage the phone display which may come to cost you at high
There are going to be 3 main factors that you want to address:
- Battery
- Charger/charging cable
- Software
It seems you have already addressed your battery. That's usually the #1 culprit, but you've already replaced it so you can rule that out.
The next is the charger and charging cable. This is often overlooked. The stock charger is 5 volts and 1.8 amps (5v 1.8a). Before more advanced smart phones were developed, almost all USB chargers never produced more than a 5v 1.0a charge (most were 5v 0.5a). So you want to ensure you are using at least a 5v 1.8a charger. (I even use my Fire Tablet charger on my G3 which is 5.1v 2.2a, and that works great too). Note that all USB chargers have their output volts/amps printed on them somewhere (usually in very tiny print). The USB cable you are using matters too. The thinner the wire gauge and the longer the cable is, the less power is transmitted. For example, if you're using a thin and cheap 6 foot (2 meter) USB cable on a 5v 2.0a charger, you may only be getting 1.0a of charge from it. If you use a thicker, shorter, and more expensive 3 foot (1 meter) USB cable on that same charger, you ensure you get that full 2.0a of charge (or close to it). The two factors to look for in a USB cable is length (length = resistance = less amps) and wire gauge (not insulation thickness).
The last is software. If you have any way to backup and restore (ie nandroid) your ROM from recovery, I recommend doing that first because it's easy. If you backup your current ROM, factory reset, and the issue persists then you know its the charger/cable. If the issue is gone, then you know it's something in your current ROM. If you do not have access to backup/restore features and/or do not have root, then next you can use the Android OS Battery stats to carefully go over what could possibly be draining so much power when the phone is on or off. There are also several apps that will help you determine where the battery drain is coming from. Note that software can not prevent your phone from charging, but it can drain power so fast, that there is not enough left over to charge the battery. This is especially bad for our G3s because they easily overheat if they are charging and heavily discharging simultaneously.
Hope that helps! Good luck! :fingers-crossed:
