Hi guys ,
After having the new battery , I try to charge the old weak battery with the external charger overnight , then use it , I notice that the power meter going down little after a day use , specifically 90% level whereas in the past I used my PDA to charge it , the power level always drop down to 55% at the end of the day . Perhaps the internal power charger of the Exec is malfunction after long period usage . From now on , I will use the external to charge the battery for my Exec .
Does anyone out there have the external charger and pls try my experimental .
Regards .
maybe the external drains the battery fully before charging it? Doing this helps keep the battery conditioned in tip-top condition. I don't have time for this and always top up as I only have the jasjar mains adapter but I used to try to leave backlight on in weekend and fully drain battery before charging it

...yes with Ni-Cd batteries of 10 years ago but the worst thing to do with a Li-ion battery
i know you can wreck your li-ion battery by going to 0%
but isn't there a safe minimum you should really discharge to?
There is NO point to discharge Li-ion batteries. That is why it has been developed. We wanted a battery we don't want to wait draining it more like to charge it anytime. So, the truth is not "we don't need to drain it" but "we must not to do it", because battery dies in a short time.
Hi everyone, i was wondering if someone can tell me if charging the battery from 10-15% to 100% its bad for my device? Also which recomendations you suggest for reduce battery damage on the device? Ive read about the li-polymer batteries and some says that is bad for the battery to leave it conected log periods of time, also other mentioned that leaving the battery till it reach 10-15% is good method for prolong its battery life, but imnot sure about this tips.
Can someone tell me some recomendations?
I know from experience, li-po batteries do not last if fully discharged everytime, meaning don't run it till it shuts off. I am charging in the 10-15% range. As far as leaving it connected to the charger, I'm not sure if thats bad. If all you did was use it while connected to the charger, yes that will result in reduced battery life due to it not getting discharged.
do i drain the battery before first charge? is it really necessary to do overnight first charge or 3-4 hour full charge will do? need to take extra care since it is non removable.
I know that's really un-educated but I'm not sure about those things as well ... is it good to drain it first and then recharge it, or recharge it at the beginning .. and is it bad when you take it off the charger in the middle of the process?
I know it depends on battery type. And actually what would make sense is just following the manual. Why shouldn't the manufacturer know?
Anyway, anyone with some knowledge on that, please help!
Nearly all cell phones use Lithium-based batteries, which should not be drained before charging. The "drain before charge" thing only applies to nickel cadmium batteries.
You should charge your phone battery as often as possible. It's better for the battery to go from 100% to 80% five times than to go from 100% to 0% once.
I have read several articles that state it is BAD to completely drain a lithium polymer battery so I plan to just keep it charged as usual.

I've heard the same info too where it'll damage the battery by draining it completely. Although, I heard that power management on devices sometimes need to be calibrated by taking the lithium battery to near 0%...it's that way on my macbook pro...not sure about phones.
Hello,
I am doing an experiment since few days ago. I noticed that if you disable the Fast Charging, and (most importantly) use a proper, thick 2A USB cable (I use a Kindle Fire original cable) then the battery lasts around 15-20% longer.
How to recognize that you got a proper USB charging cable ? With fast charging disabled and the battery empty, the phone should tell you that there are around 2 hours until full (instead of the usual 7 hours or so with fast charging disabled). That's when you know that you are using the proper cable. I bought a original Kindle Fire cable from Amazon and that is very solid, much thicker than the standard cable. See attached screenshot. With the standard cable this seems to be a hit and miss, you sometimes get the 2 hours message and sometimes the 7 hours message.
I repeated the experiment 3 times and each time I got significantly better battery life than before.
You may want to try it to see if it works for you.
PS: Attached is my latest battery life screenshot (APC8 firmware), which is the third charge since the experiment. 2 days 6 hours of stand-by with 5h SOT on a mix of 80% Wi-Fi, 20% 4G with nothing disabled (even Bluetooth is permanently connected to the LG smartwatch). Almost no videos played, only web page browsing which is quite demanding on battery.
Look if new software update is possible.
Yeah, I noticed that my battery life was worse when I used a ****ty 1 Ah Sony charger when I displaced the original Samsung charger. It took about 3 hours to charge it up to 100%, but then I noticed that the battery life would be worse than before. I found the original charger again, and battery life is back to being good again. I never use fast charging, unless it's in the middle of the day and I'm heading out or something.
None of the things mentioned above should (technically) have any impact on battery life once unplugged? I mean, stored electricity is stored electricity, so if someone QUALIFIED could give an explanation here, it would be cool.
Nothing new, I've always noticed that if I charge the phone with the original charger and fast charging disabled it will last much longer.

This cable? Which AC adapter do you use?
None of this solutions should impact battery life Oo. Energy is energy, no matter where it comes from?!
Would be nice, if someone qualified could tell us more..
Do you have the newest android version installed?
By the way, I only charge with original charger and cable, fast charge disabled (battery life is longer?!)
Battery life depends on how well you follow charging & discharging cycle. I usually fully discharge my battery (so that phone will shut down by itself after dropping below 1% charging), then charge it fully keeping it switched off & then use it.
I always had far better battery life than most people complain about.
BTW, I also tried charging battery keeping phone switched on at 10-15% charge remaining, battery definitely performed weaker for my use.
So that confirmed my theory based on my usage over last 7 years..

Yes, this is the exact cable I am using. A bit expensive, but for me it was the only cable that consistently worked at 2A over time.

I wonder if Qnovo is qualified enough ? Their technology is employed in many charging solutions. Here is what they say:
"Add fast charging - it gets noticeably worse. It turns out that the simple way batteries are charged today causes most of the damage that leads to shorter daily battery life and reduced lifespan."

So you're saying that Kindle Fire cable extends battery life? Isn't 100% battery life from one cable the same as 100% battery life from another cable? Energy is energy.

In no way I am saying this. I am just saying that you need a cable that reliably supports 2A charging, so the charger shows 2 hours to full instead of 7 hours to full, even with fast charging off.

Ah okay. I went ahead and bought one!
It ' also the logical thing. With fast charging , the battery holds less charge than the "normal . " He just spoke in various forums of this.
Anyway , great idea.
How to maintain max battery life span (reliable source):
Perform shallow discharges. Instead of discharging to 0% all the time, lithium-ion batteries do best when you discharge them for a little bit, then charge them for a little bit. The table below, from Battery University, shows that discharges to 50% are better for your battery's long-term life than, say, small discharges to 90% or large discharges to 0% (since the 50% discharges provide the best number of cycles-to-usage ratio).
·Don't leave it fully charged. Similarly, lithium-ion batteries don't need to be charged all the way to 100%. In fact, they'd prefer not to be—so the 40%-80% rule you heard is a good guideline. When possible, keep it in that range to prolong its life as long as you can. And, if you do charge it to 100%, don't leave it plugged in. This is something most of us do, but it's another thing that will degrade your battery's health. If you need to charge it overnight, use something like the Belkin Conserve Socket to stop it from charging after it's full.
·Fully discharge it once a month. This may seem contradictory, but hear us out. While lithium-ion batteries shouldn't be discharged regularly, most modern batteries are what's known as "smart batteries", which means that they can tell you how long you have until your battery dies (e.g. "2 hours, 15 minutes remaining"). This feature can get miscalibrated after a lot of shallow discharges. So, manufacturers recommend fully discharging your battery once a month to make sure this stays accurate.

But you stated that it increases battery life.

What he's saying is that a slower charge equals a longer lasting battery between charges.
But maybe that doesn't apply to Li-ion batteries, according to this link here.

You can try it for yourself (if you have an S7/Edge) and report the results here. I posted my results, I'm not an expert, I just tried this. I also tried the 7-hour slow charge (with a different charger) and it didn't work as well as the 2-hour charge. The 2 hour charge seems to work best.
Yeah, If you use fast charging the battery dies a little bit quicker. I recommend fast charging if you are in hurry.
I only use fast charge when I'm in hurry.. Nice feature! I try to charge my phone between 25-80%...

Worst thing you can do for the lifespan of an Li battery.

I disagree, even though it switches off itself, it still has charge, don't go by it says 1%.. so it's not fully discharged... besides my method served a good battery life to me over the years with earlier phone models
I've got an issue with my battery where phone shuts down every time at 30% and won't charge above 80% unless I disconnect and reconnect charger then charges rapidly to 100%
I've heard LiPo batteries are easily damaged and have a short life span. In my case it has came to 0% numerous times. I tried calibrating it and still nothing
Here is some info on the battery.
Are those mA measurement's okay or bad?
These measurements are totally normal
It's probably your rom mate

Sounds like you need to return it under warranty.
Well I tried many different ROMs and stock firmwares still no luck. I've called service center and they will fix it. I think Li-Ion batteries are far better then Li-Poly
Had that issues on my previous device, Galaxy S4. Shutdowns at ~20% battery, terrible sot. My battery went bad so i replaced it with new battery and that solved it.
Consider replacing battery if flashing stock firmware does not help.
Batteries can last long if you take care of it. I guess you tortured it by draining it all the way to 0% or using the phone while its connected on charger, you should NEVER do that! 20% in my opinion is minimum before you should charge it to prolong battery life. Also if you really want very long battery life, do not charge it above 90%.

Thank you, I will be sending phone to service center. I really was using it while it was charging and it went to 0% million times.
This is what you guys get with a bad battery

How long have you had the phone? I doubt li-poly batteries is alot worse than li-ion since both are very similar.
