I have decided to move this post from the issues thread to a dedicated one to give it better visibility. If no one else is getting this problem then I will probably return the device.
I have the excellent "devstate" today plugin application installed which gives the battery charge level in 1% steps. When I say slow, it takes around 3 mins to increase by 1% which means it will take 4 hours for 80% charge (too long) when this is the case, the back doesn't heat up.
I have seen it charge much faster on one occasion i.e. around 1% a minute and the back was warming up (this is logical if more current is flowing) I was wondering the cause of the slow charge is that the device thinks it is connected to a pc and the charging current is limited. Also when you plug the cable sometimes the menu pops up asking whether you want to enter activesync/disk drive mode but doesn't on other occasions. There doesn't seem to be any pattern to it.
Another observation is that a soft reeboot occasionaly gives wildly varying battery levels for example before reboot the charge might be 100% and straight after the reboot 90%, or 83% before and 100% after. Interestingly before turning on the device for the first time I fully charged the battery, but up on boot up it was reporting 60%! (maybe it didn't charge at all when it was switched off and 60% was the initial amount of charge the battery came with) Have I got a duff battery or some issue with the device itself?
I seems like the battery charges fast up to 75% at around 1% a minute but then slows down to 1% every 3 to 4 minutes. Maybe this is the charging profile for this battery. Has anyone else noticed this?
Here are a couple of threads from the diamond section regarding the sort of issues I am experiencing but there doesn't seem to be a conclusive fix.

Could people please answer the following questions to help me decide whether I have a faulty device/battery or some ROM issue which all of us have. I have the stock UK touch pro ROM 1.90.405.1 WWE.
1) If you fully charged the battery before powering on for the first time, what was you battery charge level immediately after power on?
2) Have you noticed fluctuating charging rates?
3) Soft reboot gives different battery charge levels.
Just a quick Q, which charger are you using? Can you just post the amp / volt data printed onto it for us?
I am using the one that came with the touch pro, model no TC P300, its output rating is 5V at 1A. Input rating 100-240V
I have also tried the mda vario III charger and I get similar results i.e. fast charge up to 75% then slow afterwards.
As i stated in the other tread with the "Raphael issues" i have the same problem.
When i use the shiny new charger with the "usb-mini usb" cable i takes 7-8 hours to completely charge the device. (output is 5V-1A)
However, when i use my good old Hermes charger, or any other 5V-1A charger, it goes to 100% in about 3 hours.
Mine charges up to 90% from 10% in less than 3 hours after which it stays @ 90% (According to the built in battery meter of the device) forever. Is it a faulty battery or its supposed to be like that?

And do you get varying battery levels on soft reboot?
3 hours is probably what I would get i.e. "75% at 1% a minute = 75 mins" PLUS "25% at 1% every 4 mins = 100 mins" giving a total of 175 mins.
question is that is this behaviour normal for touch pro or only present on
some device/battery/chargers.
I also have another issue, this time regarding interference on speaker, see this thread:
http://forum.xda-developers.com/showthread.php?t=419761
If only my touch pro has these faults then I want to replace it asap, especially when having paid £500 for it.

Yes i do get varying levels on reboot, but i got that with my Hermes and Magician too. So i wouldn't worry about it. Usually when you softreset while it's charging you get a higher battery reading then you should have, but it wil drop after some time to it's real level.

This happens when its not charging. I don't get this with the vario III. Maybe it is ROM dependant. The other concern was after having charged the device fully when switched off, it reported 60% on power up. I might let the battery drain to a low level then charge when switched off to see whether it charges at all. Some diamond owners were also reporting this.
Hmm, got the same thing tonight with my Hermes charger, has been charging for 6 hours and still not fully charged, now at about 80%. Very strange. Are there more people experiencing this?

This didn't appear to happen to me on the first charge, but I turned it on immediately after putting the battery and SIM in place, and then I charged (I don't remember what the initial battery charge was). I've not noticed such wildly inaccurate readings after reboot either. I haven't specifically checked for inaccuracy in the battery meter, but I would (probably) have noticed such a big difference.
Have you tried to do a full discharge and charge cycle? This is necessary after around every 30th charge to recalibrate the gauge so that it is as accurate as possible. I know yours probably haven't gone through 30 charges yet, but it may be worth trying.

This is normal for lithium-ion batteries. The last 20% or so can take as long as the first 80% to charge.

When charging I usually leave mine overnight, so I think I've only charged it once during the day, and then I think this was through USB while connected to the PC so it may have been a bit longer than 'normal' (3-4 hours) for that reason. I'll keep an eye at it next time I do it during the day.
Six hours plus sounds far too long though, do you have a chance of trying the battery in another device, or another battery in your device?

Nope, don't have a second Touch Pro around here, but this is really annoying, I need a fully charged battery in the morning. If this is hardware related i'd return it to get a replacement.
hmm, this is interesting.....so just to clarify we are seeing slower charging with the bundled adapter: which is essentially an AC to USB power transformer?? If the USB port on that (yes i know its power only) is capable of supplying only a standard ammount of juice then your battery may charge to 100% as slowly as from a pc or car charger..
..id like to perhaps see if i can meter the current and voltage coming from it but would need me to cobble together a breadboard with the relevent power points.
Is the hermes / kaiser charger charging it fully in less time?? (to clarify)

Yes I drained the battery till the phone switched off by itself but still have this problem. I suspect there is a problem either with the phone itself or the battery as supposed to a ROM issue. I thought all the clever charging circuit is in the battery these days and it's the battery which reports it's charge level to the device too. If this is true then probably the battery is faulty but I am not going to buy another one just to find out. I'll try to get a replacement for the touch pro tomorrow when the shops open.

It is, but even so the gauge (in the battery) needs recalibration once in a while, hence the full discharge/charge cycle every 30th charge or so (other than that it is recommended to charge li-ion batteries often, and not deplete them fully).
Your next port of call is probably to see if another battery makes a difference.

Today I charged my phone from empty to full while connected to the PC, which took around 3 hours 30 minutes (phone not used except to check charge levels towards the end).
the charging cycle on mine has been a little erratic too.
I put it on charge at 9pm last night, at 6.30 this morning it was at 88%. 9 hours and not fully charged!!...still, 3 hours later and it's on 87%. so I think its more a case of requiring a few charge/discharge cycels to settle the guage down a bit.
This night it fully charged in 5 hours. While yesterday it wasn't completely charged in over 8 hours. There doesn't seem to be a pattern in this.
Yesterday it was showing 48% battery level at one time, a soft reset later 28%, another soft reset and it was 24%. Today I have sent it back for a replacement. Can those people affected by this issue please state where they bought it from, in order to figure out whether it might be a faulty batch. I bought mine from clove technology in the UK.

Mine came from Expansys.be, please let us know your new unit has the same behaviour.
Will do if I get a replacement one, they have satisfy themselves that there is fault first. Will probably take around 3 days. I miss my touch pro already.....
Oh well back to the vario III for the time being, seems cumbersome already in comparison.
Hermes Charger

Whilst I don't have any exact figures to hand, my hermes charger took about 45 mins (Give or take a little.)
I've been using the standard Raphael charger today and charged from 50% and it's still going after 1 hour 20 mins and only at 90%
I know the final 80% takes a lot longer, but even so.....
Hello everyone
I was wondering if its ok to leave the transformer connected to the charger.
Is it like the Evo with trickle down when it reaches 100%
I dont want to over charge it. If it were my laptop i would disconnect the battery at full charge. But its not possible to do that with the transformer.
I want to keep my cycle count low and prevent over charing.
I also wonder what happens in a few years when the battery is shot...
Charging is what damages Li-Ion batteries... I'd recommend not keeping it on the charger all the time. Android will purposely not keep the battery at 100% to help avoid some damage.
Li-ion prefer to be around 20-80% charge.
When battery is 100% and you keep the charger connected, heat will begin to build up and eventually you will kill your battery.
I'd do as with a notebook: charge till 100%, then remove battery or charger (in case of the tablet charger ) . Then use your tablet and recharge when needed / desired. And from time to time a full charge / discharge cycle won't do any harm.
Just my 2 cents.
Regards.
These tablets don't automatically recognize when it's fully charged and turn off the charging?

They do. There are other threads asking why thier TF's don't show 100% when unplgged from the charger. Same as it does on my Evo.
I think pretty much every modern device recognizes a full charge and responds accordingly. In fact, MacBooks will throttle performance if the battery ISN'T kept in while the system is running on A/C.
Heat will damage a battery, but it's not heat from charging but heat from operation. If a notebook is poorly designed and the battery is near a heat source, then removing the battery might be a good idea (except with the aforementioned MacBooks), but that's independent of the charging issue.
I think it's fine to keep it plugged in. These devices are smart enough to manage such things. Of course, the TF's charging cable's so short it's hard to use when plugged in, but that's a different issue entirely.

From what I understand this process cannot and will not kill the battery. This did happen in the old type of batteries with the ,emory effect but these new batteries and the OS's management system for charging does not allow the battery to be killed.
it will heat up and that would happen as there is a flow of electricity but not to a level that would kill the battery.

IS it normal to go from 4% battery to 99% in under 3 hours ?
I thought this was supposed to take 8 hours to charge.

Yes that's normal. It's meant to take about 3hrs.

Still dont know about it. Because I think its like my EVO and technology got so good that my battery is protected.
I really dont want my transformer to become a expensive paper weight or non-mobile because after a few years it has 45 mins battery life.
I've got the first full charge and full depletion done. Is it ok to use while charging now as long as I fully charge and fully deplete it a couple more times?

batteries will degrade over time....would you be keeping this tablet for over 2-3 years? a simple battery change could work if ever needed
I am no expert, but I have spent some time searching around the internet looking for information on the best methods for improving the life of a battery. Most of the information I have found said it is bad to completely discharge a Li-polymer battery. The articarles stated it was best to charge the battery when it reaches 20% to avoid shortening its life.

Batteries are like muscles - they like to be exercised.
Leaving the unit plugged in WILL NOT HURT YOUR BATTERY. Period. The charging circuitry in modern devices is smart enough to cut current to the battery once it has reached a certain level of resistance.
Batteries do not like being deeply discharged. Most devices will shut off before the battery gets too deeply discharged, but it's never a good idea to tempt fate by running it until the device shuts off.
What really determines a battery's life is the number of cycles it has been put through. A cycle would be a full charge followed by a full (or to a lower end threshold) discharge.
The old original Lithium Ion batteries used in laptops would usually last about 300 full cycles or so - about a year if you used it on the battery every day. Partial discharges of course only count as fractions of a cycle.
Given the life of these types of devices, considering we'll likely upgrade to the next big thing in a year or so, I don't think anyone here will come close to 'wearing out' a battery.

As stated, these are Li-Ion batteries, and they do not need to be trained. The only reason you might need to do any training is to calibrate Android's understanding of the battery (although I doubt you need to do a full discharge for that, either).
It's not going to suddenly kill it, but it will over time hurt your battery's life.
I went ahead and did a full discharge/charge cycle, but only because Asus said to do so in the manual. Maybe the copywriter just copied/pasted from a circa 1990's manual for a device with a NiCd battery, but I figured if they're suggesting it, I might as well do it.
Trickle charge kills battery. If you arrive home late, put your phone on the charger and charge it overnight it kills battery.
It would be cool if it was possible that an app could cut off charging at ~80% when trickle charge kicks in. Maybe root is needed but is it possible at all?
Or a physical timer which cuts off charging after a certain time (2 hours to charge from 0% to 80; 1 additional hour to trickle charge from 80% to 100%).
Any thoughts or solutions for this?

Exactly that. Thanks.
Personally I use a powerpack to charge my phone overnight. Once the device is full, the powerpack stops charging.
Admittedly I have to remember to recharge the pack every week (it's 15600mah), but on the other hand I can also bring it with me. It's also safer.

If you're rooted, I know some custom kernels (I want to say I saw it in the Aroma installer of ElementalX for my Nexus 7) have an option to cut off charging around 95% for this reason.
But of course, that's only if you're comfortable rooting and tinkering with kernels and such.

I don't think there is really a set time, its just that when it starts to go just replace it.
I'd usually do it within 18 months so you're on time for a replacement. Batteries don't last too long which is why buying a sealed battery phone is ridiculous imo.
Depends a lot on how you charged it over the years. Some people say it's better to charge those kind of batteries often and don't let them get below 20% or 50%. And If you use your phone while it' charging, that also decreases the life of the battery. High heat or cold also take some time off the battery's life.
Even if you do take good care of the battery, it will inevitably lose it's capacity over the years.

I feel the same way. But maybe nowadays ppl change phones pretty quickly, so by the time the battery's about to die, they're already getting a new one.
I have been using my phone for almost 2 years, and it already loses its charge so i decided to change it. I think it depends on your usage, if you use it for heavy use, it will loses its charge faster.
I bought new original battery after 12months of using old one,with daily usage i can get around 5hours of screen time

Well after 2 years, any good old battery will be singing on the last verse so to speak. Time to change it. Just normal!
My phone is about two years old now and I thought I needed a new battery. Instead I picked up a new samsung charger (the one that ships with the Note 4). I don't know if it's because of the increased voltage output but my phone seems to hold a charge better - and charge faster!

In general, the deeper you discharge the battery, the fewer times the battery will recharge. If you use your phone heavily, and always drain to 0% almost daily, that will result in a battery that will stop holding it's charge very quickly. However, if you don't use your phone heavily, or have access to a charger throughout the day to top up your battery long before it crosses 50%, then it will typically last a lot longer.
The fact that you notice a significant loss in battery performance, most likely means that the battery has either lost significant life, or at least significant enough to how you use your phone.
You may try the "Battery Calibration" app from google play store.
it's free but require root access.
This app remove the batterystats.bin system file. The OS generates a new clean batterystats file soon.
It's like you're refreshing your battery...
Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated.
I use this app myself and it's great...
hope this help..

Read the last paragraph. Battery calibration apps don't do anything except generate a placebo effect and screw up your battery stats. To maximize battery life, you want to examine what processes are running and kill the ones you don't want to run, using Greenify or Autostarts.
I decided to replace battery after 15 month of intense use.
My S4 had the same problem. I reset the battery stats, and after that it works great now. Battery easily lasts for a full day.
Here's how you do it.
*Let the battery discharge while doing normal routine stuff, until it switches off.
*Turn it on again and use it some more till it switches off again. Repeat, until it wont turn on any longer.
* Remove the battery and hold the power key for 30 secs or so with battery removed(I do it for upto a minute)
* Install the battery and close it up and now connect the charger.
Let the battery charge to 100% WITHOUT turning the phone on.
*After 100% is reached, turn the device on and disconnect the cable and use it as you normally do.
DO NOT RECHARGE in between and let it discharge completely or till the point, it'll just be about to turn off, then connect the charger.

Calibrate your battery. . If you don't have the app .. charge til you get to 100% unplug charger then turn off phone, plug in charger while phone is off. . Charge until it's green. . Unplug and turn your phone on. . Repeat that process 1 more time and it will work
I just bought a new OEM battery from Samsung. What should i do first? Charge it with phone turned off to full then discharge it to 0 and then charge again to max? Do this one time or 3? maybe there is some article about what u should or shouldn't do when u get a brand new battery?
Hello sohail
My s4 has only average battery timing. Which is not enough for me. Plz suggest me some solution.
Hey guys, I am so insecure about the battery charging tips for the OnePlus 6. I've seen a lot of posts, some say it does no harm charging to 100% and vice versa. Could anyone please enlighten me? I always charge my phone until 80% and then disconnect the power source.
Thank You
Whatever makes you feel comfortable.
I always charge to 100% but try to avoid the constant use of dash charging. I find that regular fast charging slightly reduces the battery life. Not charging to 100% also reduces the battery life (as the phone will think after a while that 80% is the max it can reach). I want to keep this phone for a long time (got the 8/256 version) and my experience with years of computerized Lithium chargers (for RC stuff) suggests that a. always charge to 100% and b. avoid frequent fast charging, slow(er) charging is better. That lead for me to the max battery life (both capacity and overall life expectancy)

Not charging to 100% will NOT reduce battery life as much as charging to 100%. You're probably thinking of Lithium-Polymer batteries and not Lithium-Ion batteries which this phone uses.

Ignore all the crap. Just use your phone comfortably as that's how the experience should be. By the time your battery degrades, you'll probably be looking to replace it anyway.

You may be right. I am not sure. What I do know is that I sold my last three phones after 12-18 months of use and using my method their batteries had the exact same capacity than the day I got them. My wife is charging her phone whenever she feels like it (most of the time she charges to less than 100%) and after less than a year the capacity is reduced.
So I am not sure if I do it right (they way it "should be done") but it works for me.

It's 2018 battery technology has changed. Charging it to 100% is the same amount of wear as having to charge to 80% more often 1 cycle on a lithium ion battery is how many times it is charged to 100% total. So a charge from 25% to 100% is .75 of a cycle then if you run it down to 75% and charge the 25% back to 100 that is 1 total cycle. It doesn't matter how many times you go to 100% or how many times you plug it in. And dash charge has built in protection against overcharging and it also slows charging when it nears full capacity. So Dash charging isn't any more wear than a slow charger.

Not charging to 100% will NOT reduce battery life as much as charging to 100%. You're probably thinking of Lithium-Polymer batteries and not Lithium-Ion batteries which this phone uses.

It won't reduce the battery life and neither will just going to 100%
See https://batteryuniversity.com/index.php/learn/article/how_to_prolong_lithium_based_batteries
BTW.. my battery is often hot, running at 30-31c. What Temperature is your battery at when not doing much?
as you want
Just bear in mind your battery will not have the same performance after 2 years of use.
just charge it up to the level you want, then invest in a $30 replacement battery.

I always charge to 100% but try to avoid the constant use of dash charging. I find that regular fast charging slightly reduces the battery life. Not charging to 100% also reduces the battery life (as the phone will think after a while that 80% is the max it can reach). I want to keep this phone for a long time (got the 8/256 version) and my experience with years of computerized Lithium chargers (for RC stuff) suggests that a. always charge to 100% and b. avoid frequent fast charging, slow(er) charging is better. That lead for me to the max battery life (both capacity and overall life expectancy)

How do you not do dash charging if all you got is the charger that came with the phone? Is there a way to actually tell it how to charge the battery?

I have about a half dozen phone chargers - I just use one that is not dash
i emailed oneplus and they told me a new battery after warranty cost only 33 euro including repair and shipping so now that i know this i dont really care about my battery health and will change it out around 2 years
I'm changing phones every year. By this time battery will be fine, so I don't really care how to charge it. My way is to charge it every night with USB cable connected to pc (slow as f*ck, 80% takes about 3 or 4 hrs, but sleeping takes6-8hrs anyway - reason for that is stupid I don't have power socket close to my bed ) - in case I need juice fast - two oneplus chargers somewhere at home.

Hey guys, I am so insecure about the battery charging tips for the OnePlus 6. I've seen a lot of posts, some say it does no harm charging to 100% and vice versa. Could anyone please enlighten me? I always charge my phone until 80% and then disconnect the power source.
Thank You

You should charge your phone to 100% and if you can leave it on a charger even after that, even better
I'm actually a developer and have read the code so please read on for the explanation
If you have had a phone with android M or lower you might be familiar with the "android is starting/upgrading" screen where it showed "optimising app x of total"
So, Google removed that code in N right? Why is this a bother
Actually wrong, that code was simply relocated
The code was moved from the boot process to when the device was charging (that is, plugged in), full charged (that is, 100%) and idle (idle = device is not physically moving)
Once this condition is satisfied, the code behind the "android is starting" screen runs in the background and starts optimising apps
In other words, you have to keep your phone connected to a charger in order to finish this process
Which is why it is a good idea to charge overnight
What if you don't allow this to happen?
Ever heard of the classic "android system using a lot of battery" issue? You basically force your system to use the JIT compiler which uses a lot of battery and android system comes to the top as a result
In other words if you don't leave your device on a charger long enough, your battery life will suffer anyway
Wiping cache is also a pretty bad idea
So, leave your phone on a charger without worries. Google just made the "android is starting" code a lot more convenient for the user but you have to allow your phone to run that code otherwise it's meaningless
Protip: some root users suggest running "cmd package bg-dexopt-job" in a terminal emulator app as root forces the optimisation to happen. I haven't personally tried it but it won't cause any damage to your phone that's for sure
That doesn't mean you should go try it unless you are aware of what you're doing either

What if I charge for a prolonged time but the battery doesn't reach 100%? I.e. if I plug it into my PC (very slow charging) and leave it for a few hours?
