The S2 takes forever to charge the battery. Coming fron the iphone 4 i suspect this takes ay laeast twice as long to charge!
Considering the battery performance isnt that great, this is a double whammy!
What do you guus think?

Yeah, I noticed the same thing. I'm always charging it when I'm at home to keep it fully charged, in case I'm going out.
charging takes me about 3hours (from empty). It is stanrard time
Same here for charging. Between 3 & 4 hours. But battery life is getting better especially if i disable 3G and wifi

Im using nokia charger 1.2A and HTC charger 1A and also i have 0.7A all of them takes about 3 hours may be hardware bug?
I've been using a BB charger for it, and thought maybe that was the reason. Glad to know it isn't.

Yep, I confirm.
Charging takes around 3 hours.
I can use it almost 48 hours before it needs to be charged again. So it is not really annoying.
Stock SGS 2 with official battery charger and a full drained empty battery 3.5 hours to charge to 100% .

About 3 hours here which is fine, charging from the supplied charger connected to electricity mains. Are you charging via the USB connector? It will take a lot longer, something called trickle charge or something like that.

No it takes the normal time but if its to slow for you dont drain it or sell it .

I noticed this when my brother bought the same phone. His takes a ridiculous amount of time to charge, maybe 1% per 10 mins or so and it gets really hot while doing so.
Mine on the other hand doesn't get hot at all and charges at least 3 times faster than his.
please state charge state, ages, fast normal etc.
firmware and revison thanx
The charger shipped with my S2 has only 700mA...
especially if you are using the phone (worst: gaming) while charging it seems to get never finished . I guess the current drain doesn't left much for the charging.
So i'm using my old HTC-chargers (one AC=>USB and AC=> MicroUSB) witch both supplies 1000mA.... ~43% more in theory
Hard to say how big the advantage is in fact, but it makes a difference.
Also keep in mind, that a standard USB-Port supplies max. 500mA, depending on other USB-devices even much less. I also read that the charging result is "better" if you not using it in the meantime.
You can buy USB-Chargers up to 2100mA (e.g Amazon), but i have doubts that this will be improve the charging time because on the type-label behind the battery is written Rated : 3,7V-1000mA. Even more current wouldn't not damage the device (afaik!!!), the device or the battery could not charge faster.
Maybe somebody knows about what is meant by the the 1000mA exactly. Would be nice if the device could be charge a little bit faster.
Otherwise i am going to buy a 2nd battery with an external charger.
greetings
I found this on Android Forum

USB charging is slow on the S2 as it uses trickle charging
"Trickle" is an exaggeration.
The phone can tell whether it's connected to USB or a mains charger. If the latter, it limits charge current to 650mA. If the former 400mA.
It will charge faster on the mains but not loads faster.

My other cell phones are fully charged in 2 hours, more or less. And yes, I'm considering selling it, because I like to use my gadgets and the SGSII doesn't admit an intensive use without running out of battery, unless you have a second battery.

Yeah, I do sleep more than 3.5 hours per day and I try to charge it every night, but the problem is when the phone runs out of battery in the middle of the day and you don't have 3.5 to spend in charging it fully.
I think the iphone 4 is only a 1420Mah battery if I remember correctly while ours is 1650. Sure, it takes perhaps another hour to charge but I don't find it a big deal. It does appear that the first 50% charges faster then the second half as well but that could just be my imagination.
I have read that Samsung phones charge slower so that the battery life will be longer than that of those other phones such as HTC where the phone charges a lot faster. I'd rather get another year out of my battery and it take longer but do admit 3.5 hours does seem like a while.
this topic has been covered. teh SGS2 battery driver is capped at 650 mA for wall charging, 450 mA for USB charging. this code resides in the battery driver.
someone could compile a new kernel with this value raised. other phones like the nexus one charge at 980 mA for wall charger, 480 for USB.
samsung capped charge current, likely for heat issues, nobody really knows.
same. take long time to charge and heating if charge n gaming. the hottest spot at camera side

Hi guys! Just got this baby today and battery is dying soon! Just wondering if you guys let it charge overnight for 8 hours on the first charge?
It'll take 3 or 4 charge cycles to reach full capacity. And by soon, how many hours of screen on time are you talking about?

Well I was just asking if you guys charge it straight for 8 hours on it's first charge lol :X
Electronics inside stops charging once the battery is full. You can leave it on forever it won't make a difference.
You can charge it while turned off (maybe one or 2% more will go in) but other than that don't worry about it.
But yes, first couple of cycles are aweful, use it for a week or two, then the true battery capacity will reveal itself.
Also you might wanna discharge it to auto-shutdown and charge it up to 100% uninterrupted for best results.
To answer your question quickly: no, I only charge new devices until they're full unless I leave them overnight.
If you do some math: 4325mAh battery being charged at rate 2A (that's the official charger right?) theoretically it should take 2h10m to fully charge the battery. Of course there are losses and everything but it shouldnt take more then 3 hours.

Avoid using extended battery life.. Charge your phone til 100% and used it till gets to/around 10% and then charge it again so that the charging cycle is fixed. If you are rooted make a full wipe and install any ROM you like with some good kernels out there that matches the ROM. :good:
It might also be a rough app that you recently installed. Use BetterbatteryStats or Wakelock detector this will show you what is causing the unwanted deadlocks and causing battery drain. :good:
Hope this helps you.
Press thanks I helped you.
Hi I'm new to nexus 4 and have a battery question. I didn't want to start a new thread. I bought a slightly used nexus 4 and charge it to 100% after only a minute of use it immediately starts to drop. Is this normal? I ask because I had an HTC sensation that I charged to 100% and could at least get 10 minutes of use before battery started to drop. Is there something wrong with the battery or is this just the way the nexus 4 operates?

Nexus 4 works this way.. Its all right if battery drops in a minute.. There are plenty of process and their corresponding syncs that actually causes the battery to drain.. Try some different kernel all are good you will get more battery backup.:good:
BUT Stock Rom + Stock kernel are THE BEST.
Maintaining battery health requires a bit of a balance. You don't want to frequently do deep discharges, but you also don't want to charge your phone every time it drops by 10%. If you're sitting around with a charger, plug your phone in when it hits 50%, then let it charge fully before unplugging it.
Overall though, batteries just degrade. You're not going to have a huge impact on the health of your battery unless you're charging it every time it hits 95%.
How about using a slower charger over night? I believe the OEM is what, 1.2amps? I have a couple 1amp chargers from previous phones I had. Will that charge slower/safer?

Modern lithium ion batteries are fairly robust and more chemically sound than early rechargeable batteries. However they do have a finite number of charge cycles.
But you have to understand what a charge cycle is, a full drain to 0 and charge to 100.
So for example Draining to 50 then up, then 50 again then up= 1 charge cycle.
So... Draining it to 95 and bumping it to 100 would take 20 times to reach 1 charge cycle.
Trickle charging vs the oem power used isn't going to make much difference either.
Being ocd about the battery is just going to make you pay more attention to it and thus making you more aware of drain...just use the darn phone and enjoy it!

there is no right way. plug it in when you need a charge, or when there is just a plug around and you want to top off. you do not need to discharge battery to a certain point then charge. just charge it whenever. all these other theories are just that, theories. at work all day, i bump charge it whenever i reach around 80-85%. my battery has not gotten worse. and when im not around chargers, my battery is built to last. i average around 5.5-7.5 hours screen on time, depending what im doing, and im a heavy user.

truth.
The battery will only be able to take 1.2 amps or what ever, for the first 10% or so of battery life. By 25% charge, its only sucking around 750ma, and by 50% you are lucky to suck a half amp. Lion batteries do not charge via constant current, they charge via constant voltage (with the voltage dropped for 25% battery charge or less due to over current). So as the battery charges (aka increases in voltage) it draws less and less current.
You want a tip from a guy that has to run the lion battery analyzer for flight modules, keep your battery between 15% and 85%, and long term story them around 30%-40%. A pack that is left on a good charger ($75 or more) charger and never gets below 98% will loose its capacity at double the rate of a pack that floats above 15% and only gets charged to full when needed.
Ive had packs in the field coming back for recal from 2003 still holding above 90% rated capacity because they dont leave them on the charger and dont let them go dead in a locker some where. On the other side ive had 2 year old packs come back that are at 80% capacity ( i fail them at 85%) or less because they sat dead for a year.
I bought a new battery and calibrate it but when I fill up to 100% off the charger and the batteries will decrease by 1% every few seconds.
Does anyone have a similar problem and how can I fix it ?

Those are new? That doesn't sound right. Does the battery have any visible bulging on it, for a test try spinning it on a table, if it spins easily it's bad. Another thing to test would be to charge it to 100% either externally or with the phone off, then to test it's current charge with a multimeter, it should read around 4385 mV give or take a bit.

I've got the same problem. I have 3 genuine batteries and 2 extended batteries from MPJ which worked really good at first then after 2 weeks. The battery life of my S5 is getting terrible. It's already 50% with 30mins screen on time with small usage like browsing but I do have 4G on all the time but it used to be that I can use the phone all day with no problem with 4G or WiFi on all the time.
Does anybody noticed the battery health of 6t draining faster ..

After 4 cycle of accubattery app it shows around 3600 mah battery but my phone is brand new its been a 10 days till i bought .. is my battery faulty or is it okay ?

Same here. Battery quickly drains to 96% after unplugging from the charger. Takes half an hour max without using at all. After that normal drain.

May be new update is buggy ?
Since the last release I decided to stick with Nova Prime and no Google Companion. Before I was on stock launcher and turned off shelf. Charged to 100% and over night battery drained to 99%.Right now I am at 77% with 2 hrs of screen time and been unplugged for 16 hrs.
I would think that shelf or Google Discover is a battery drain for sure.

I don't think so. It's happening on custom ROMs as well. For me it started from one day on another. Weird thing but I think that's the ACTUAL capacity of the battery. You'll actually never have 100% battery when unplugging from the charger after some longer charging. It just shows you that.

I noticed as well. I think its because of my extended use of fast charging as isn't good for the battery. But I thought that the heat was going to the charger and you should use the charger that comes in the box.
However, from extended use of my 6T and my previous phone the OnePlus 3. Dash charging affects the battery even though heat doesn't go to the phone, it affects the battery health. And you shouldn't use it especially if you want to keep the phone for 2+ years. I've been using my 6T since December and my battery health is around 70%?! I only been using dash charge as well for both of my 6T and OP3. The reason I upgraded was because of the degraded battery in my OP3. From this, I'm gonna send my 6T back to OnePlus for a battery replacement, so that I get a brand new battery and from now on I'm never gonna use dash charge and instead gonna use quick charge 2.0 chargers as I don't have a apple 5V charger. But this should still be better for long term, even if it is a form of fast charging. All Samsung phones since the S7 have been having this quick charge standard. Using fast chargers is convenient, but it is not good for long term and it is just another scummy way for companies to reduce the longevity of your device and make you buy a new one. Tbh Dash Charging or Warp Charging or any fast charging should only be used when you're in a rush and you're phone's battery is low

Thanks buddy noticed this issue too .. while charging on regular charger it's fine shows almost 3700 as health but on dash charger it shows much lower
So i figured something interesting ...
The ideal capacity of oneplus 6t is 3700
But rated or we can say usable capacity is of 3610mah ..
So according to that accubattery is almost right ...
Hey!
I got a new device one week ago. Felt the same. As soon as I unplug, it starts to tick. Battery backup is up for 24 hours only. But I have seen many say that it lasts longer. Suggestions? ? I did one update after getting the device. That's it. Even before it was the same situation.

It did for me at least. Otherwise it's an app issue.
I only have the "issue" that battery goes from 100 to 96% fairly quick but I don't really care. Drain afterwards is normal and getting over 10hrs SOT easily anyway.

Mine does this but I noticed that if I reboot my phone every morning before taking it off the charger, this issue goes away. So I'm guessing there is some sort of trickle charging happening once the batter reaches capacity. I also notice if I take the phone off the charger as soon as it hits 100%, battery does not drain to 96% quickly as well. Must be something with the way one plus software works with charging
