Battery heat - G3 General

I just want to let you know about my observation on the issue I have for batteries for my g3 now the two stock batteries heat up much more then the trend on batteries I have. The trend on batteries never go above 32°c even with moderately heavy use as where the stock batteries heat up to 36 to 38°c with the same use. I don't know what the difference in them that could cause the stock to hear up more then the stock but I just wanted to point out my observation

best battery charging method

Just got my phone today, and the battery is almost dead... so i want to know how to charge it to get the best battery life possible
Thanks
Well it's mostly about not putting to much strain on your battery and it not getting to warm. It's better to make small charges more frequent that it is to totally drain your battery and charge it. Though I wouldn't worry to much about the newer generation of li-ion batteries are pretty decent either way.
The best way would to charge them in a cold place while they are not in use, and are therefor not a suitable way for your phone. If you want to use your phone anyway

Cold also drains your battery, maybe even more than hot. I'm not an expert in this area, but I'm not sure the small little charges would benefit you that much.
lithium batteries are not really affected by cold temperatures, unlike nimh and nicad batteries
when I got my I was disappointed too.. try some roms...
go to "Galaxy S II Original Android Development"...
Now I'm using Cognition S2... My battery life is about 2 or 3 days...

Li-Po battery?!!!

I was reading about Li-Po battery's, and I found out that these batteries might over-charge and go ka-boom.
Is this true? Does anyone have any knowledge with these batteries, and is this at all a Draw back for the N4?
Edit: Okay, so I was just scoping around and I think this source might be incorrect, but it seems like recharging these batteries have precautions, like certain time-limits. Maybe this is for removable batteries, but none the less these batteries seem more complicated than Li-Ion.
Here's a guide for charging Li-Po's that states overcharging is bad: http://www.ehow.com/how_6049668_method-charge-lithium-polymer-battery.html

Aren't Li-poly batteries actually safer than Li-ion?
That's the Technology used on Mac Book Pros and the iPads ... They are supposed to have faster and longer charging cycles among other advantages like being lighter and have more accurate power readings... But i could be wrong so please correct me if I'm misinformed ?

See that's what I tough too ?
Don't wanna start a war here but the battery on my new iPad it's fantastic ! Even on LTE I get like 2 days plus of heavy use..
LiPo or Lithium polymer batteries have a much higher power/weight/size ratio then typical Li-Ions, which makes them awesome for portable devices. The downside is that they are very temperamental as far as discharging and charging goes. Cells need to be leveled and managed independently when charging, punctures in the battery can cause it to catch fire, and have been known to create explosive fireballs when overcharged.
While it is true that over-charging a LiPo can make it catch fire, there will be controllers in place to prevent this from happening. These things are quite fussy. Even letting a LiPo drain below a certain percentage can be detrimental to the health and longevity of the battery, 20% of the battery's total capacity is often regarded as the minimum safe charge. It is also recommended to keep a 50-60% charge in a LiPo if storing it for long periods of time.
Fortunately, there will be a LiPo controller on the phone which will manage all of the dirty work for us. I imagine a ~20% charge on the LiPo will be regarded as 0% for the phone, as to not allow the battery's voltage to drop too low. Charging will be managed with independent cell leveling, and it will make sure the battery is not over-charged.
I really do not believe that, as a consumer we will have to worry about the battery or how its charging. We will just get to enjoy the awesome battery life associated with the LiPo.
Awesome thanks for clearifying it for me. You said that 20 percent might equal 0, so does that mean 2100mah will be cut short?
LiPo batteries are awesome. I still have my SE K750i and the battery life, despite over 4 years of use, is still amazing. I don't use it anymore but the battery still seems to keep most of a full charge unlike other cell phones (Siemens C65) which cant even maintain enough charge to power on after charging.
I don't think you would have to worry about the 2100mAh rating... I fiddled around with RC vehicles before and I ran one off of a parallell pack of Lipos, that should equal 10Ah which gave me about 1 hour and 45 minutes of "play time" with my truck(brushless outrunner motor and a mamba monster). It should be noted that after those 1 hour and 45 minutes the batteries still held up pretty well but the motor was glowing hot, never had any troubles with anything until I torched the motor because of the prolonged runtimes I was getting...

Interestingly, if you go into device info (*#*#4636#*#*) and hit battery information, it lists the battery as using Li-Ion technology, can anyone else confirm this? If so, there may be more to this than just a LiPo battery.

Wireless charging. Over use of

Is it best to do long charges then let it drain, or is it safe to for example use the phone ten mins and put it back on the mat for ten then use again and so on. Does constantly charging mess things up?
Thanks.

Your phone's battery should be fine as long as it's not overheating.
Most of today's batteries are built to last, which means if you are actually abusing wireless charging, you will start noticing not before 1 year from now(estimated.). And by then, most people have switched their devices. Therefore, it might be damaging you battery, I'm not an expert, but you should not start seeing any bad impact on your phone in the near future.
Other people's opinions might be more helpful than mine, but you should keep this in mind.
Cheers for your opinion. All are greatly appreciated.

Right on, and by this time next year the OEM batteries will be cheaper and thus just replace them

Almost no one charges batteries the ideal way.. well, because it's inconvenient to do so. Fortunately battery technology is getting better every year, batteries take longer to wear out and are (slowly) getting cheaper to replace when it comes to that.
The ideal way to charge a battery depends on the type of battery. The S5 uses a lithium ion batteries. Ideally you would charge a Li-ion battery slowly, not deep cycle it, protect the battery from hot environments and (idealy) stop charging around 85%.
Heat is the major enemy, battery life is shortened by a factor of two for every 10°C increase above 25°C. High cell voltages and cycling would fill out the top three list of things you'd like to avoid to maximize battery life.
So what does all that mean? Frequent wireless charging is beneficial if your battery charge is < 85%, because you don't want to deep cycle and slow charging (which wireless is) is better than a fast charge cycle for battery life. And a moderate stress if you are charging it when the battery is > 85%. Do what you can to avoid high heat e.g. don't leave your phone in a very hot car on a sunny day if you can avoid it. And if you go Skiing or store your phone in a freezer for some reason.. let it warm up a bit before trying to charge it.
Most of us will charge our phones even if the battery charge is > 85% though because we want to maximize run time, even though the higher voltages above 85% are a detriment to battery life. It's a trade off between utility and battery life. Battery life is conservatively specified around 500 charge cycles these days.. but that is a loosely defined term with a lot of associated variables. Depending on how you use your phone.. your battery may go six months, a year, even two years before you notice that your run time just doesn't cut it anymore.
I'd say don't worry about wireless charging. Charge it as frequently as you like. But try to keep your phone cool (out of the sun) when you can.
.
Cheers for that appreciated. However wireless charging on my setup involves a fair amount of heat
Wireless charging is relatively inefficient. Which means that there will be some waste heat generated. But it varies substantially on the brand of charger and whether you are using an resonant or inductive design. My wireless charger produces minimal heat.
Unless you measure the temperature.. it's hard to gage whether the heat from yours is a serious issue or not. Mine increases the surface temperature ~ 5C.

Would you mind sharing which charger you use?

How good are you with Orcad and a soldering iron?
I built my own @ 3.57 Mhz, which is also a non-standard (but very efficient) coupling frequency.

Lithium-ion battery nowadays does not have memory effect. So constant recharging and disconnecting is fine.
Cheers folks.

[tips] to increase battery life

not talking really about sot here, but about the battery health over months/years
I can read some posts where people report a very bad sot, when the Z play is normally a very good device regarding battery, There are several possible causes of course, the rom, the apps used... and battery degradation over months.
According to a studie, a lithium ion battery loose 10% every 250 charge cycles, there is some rules to help to not loose more :
A partial discharge reduces stress and prolongs battery life.
- avoid charge over 90%
- avoid use below 20/15%
- Battery lithium ion hate heat, so when charging avoid use your phone, can add heat from cpu mostly with games, and you will charge/heat longer
- the turbo charger make the phone heat like hell, and again lithium ion batteries can't stand the heat, it's a fact, Somes will say it's normal because it is sold like that. I won't take the risk if not needed, so i use only the turbo charger when urgency, otherwise i use my lenovo tablet charger (5,2v / 2A), that charge quite fast too with no heat at all.
I wish there was an option to turn off fast charging like on Samsung phones...
I don't know if we got different phones, but I always charge phone with stock turbocharger and its never hot - when I'm not using it during charging is not even warmer than normally, when I use phone during charging it's little warm.

really ?? mines heat a lot too with turbocharger and without using it during charge
Mine too, but i put it on the stone cold floor and it's much better. You should do this.

I suggest following[1] battery charge limit app ... It works fine ( root required )
[1]
https://forum.xda-developers.com/android/apps-games/root-battery-charge-limit-t3557002/
or just use a regular 1A/2A charger at home and only use turbocharger on the go
I've also done research into this, as this is the first phone I want to keep more than a year and a half. My conclusions from multiple sources are as follows (quite similar to your findings):
- Don't charge over 90%, but really you shouldn't charge past 80-85% (choose your percent based on how much you will need for the day)
- As you said, don't go below 20%, but really you shouldn't go lower than 40%.
From what I can tell, the 80-40 rule seems to be a legitimate and fairly reliable rule of thumb for smartphone batteries (don't go below 40%, don't charge past 80%).
Battery University has a lot of good info, and they state that smaller discharges and recharges are generally better for the battery. I've been able to get a full day or two of usage from my Z Play by starting with 90% and not going lower than 35-40%.

Battery longevity with Dash charging

As a first-time owner of an OP phone, I am really amazed with both battery endurance and charging speed.
However, I am a bit concerned about the battery longevity by using high V/Amps during charge, especially as the charging speed is not a top priority for me (most of the times).
As I still can't shake the habit of overnight charging, I was thinking about using an weaker / non-OP charger for overnight charging.
So, does anyone else share my concerns?
I've owned the OP 3 for two years and I've been using dash charge every night. The battery life is still good and I could get through the day. So I'm not too worried about it.
The current conversion is done by the charger and the cable, not the phone
The shorter charging time will produce less heat
=> Theoretically, it will help the battey's longevity

Yes. I almost always slow charge all my devices. When slow charged my devices last longer on that charge. Even at 0.5 amp it still doesn't take that long to charge my 6T.
The battery degrades due to heat since Dash takes most of the heat away from the battery and puts it in the brick we should be fine and to mention the battery management controler will only draw the power it needs and won't draw over the limit so no issues there. But coming from previous OP devices I've noticed the Battery quality isn't as good as other OEM's and definitely degrades much faster but OnePlus will replace the battery very cheap or you could do yourself if you can source an OEM part and adhesive
