[Q] Battery - Galaxy S I9000 Q&A, Help & Troubleshooting

How long does it take your battery to recharge (mains charger) from <10% ?
How long is it supposed to take?

erm, when i first got it prob 4 hours, now about 1 and half?

Cheers. Thought I had a duff battery there for a minute.

its Lithium ion, apparently performs better if you 'top it up' so if its on 60% and you by ur charger, plug it in. complete opposite of what i was used to with my lith polymer

How many times you can charge a Diamond battery??

I red last week somewhere that a liion battery lifetime isabout 300 times charging, does anybody now or this is true?

You can find there answer to your question..
The life span is dependent upon aging (shelf life). From time of manufacturing, regardless of whether it was charged or the number of charge/discharge cycles, the battery will decline slowly and predictably in capacity. This means an older battery will not last as long as a new battery due solely to its age, unlike other batteries. This drawback is not widely published.

same, my diamond is connected about the same amount of times per day, and then left on charge when im at home to ensure i have adequate battery, eek!
I think the 300 times charging is refer to 300 full complete cycle of charging. It need to be refer to complete a cycle from fully discharge to fully charge. If you charge your battery from 50% to 100%. It is only 1/2 cylce.
Anyone can correct if i'm wrong.
I think a complete discharge counts as 1. If you charge the battery now and then without letting it discharge completely it will last longer. This is quite Li-Ion specific.
In heavy usage a battery lasts for 2 years easy.

Even when you charge it 2 times a day? This should mean about 1400 charging?

Right, firstly, forget anything that has been written above. 300 is crap. (the film '300' isnt tho)
lithium ion batteries generally last longer when kept topped up, rather than cycled.
The batteries in out Diamonds are lith ion, but have been specifically designed for top up charging, therefore last longer.
you can expect your battery to last for 3 years of continuos use, unless there is a fault or it is damaged. It will slowely deteriorate over time.
I have just bought a new battery for my laptop, which is Lithium Ion, as was the original. This is after 10 years!

OK. I know it is out of the topic, but i still want to say: My laptop which is a precision workstation laptop's battery only last 1 year.
So, it is fair that if you discharge and charge frequently, it will deteriorate faster. This is fair enough.
Li-ion battery life - the facts
Skipping back to the facts for a moment.... the HTC Diamond standard battery is a Li ion battery with Co chemistry.
1. Li-ion batteries last between 300-500 deep cycles (from 0% to 100%).
2. Partial recharges are good. A partial recharge from ~25% to ~75% is less damaging than a recharge from 0-100%, and only counts (roughly) as around 1/4 of the impact of a deep cycle. Li ion technology has no charge memory effect, which means that the battery capacity is completely unaffected by partial charging (n.b. this is NOT the case for NiCad or NiMH technology).
3. Li-ion batteries also decay at a constant rate over time, dependent on temperature, and regardless of use. They lose around 20% capacity per year at 25C, but this is increased at higher temperatures. Shelf life is optimised by keeping unused batteries at 6C (fridge temp) and with ~40% charge. But do not freeze them!
4. 100% charge causes accelerated decay rates. So keep your battery below full charge.
5. Deep cycle the battery occasionally (~once per 30 charges), to recalibrate your charge meter. Otherwise the charge level shown will become inaccurate.
6. Key advantage for Co chemistry is high energy density - up to 200mWh/g. Key disadvantage is the charge/discharge limit, which is ~1.2 coulomb.
7. Conclusion is that you can expect your Diamond battery to last for ~3 yrs of hard daily use. If you take care of it, it will last for double that time.

Stock battery "unstable"

so for the short little while, in the span of 5 minutes, i've been trying to gauge the Voltage capacity of the stock battery when at 100%
it has jumped from:
4.118 V
4.162 V
4.123 V
4.166 V
4.170 V
and then back down again...
4.170 V
Can some one confirm how much battery we get when the battery is fully charged at 100%?
i was trying to compare the stock vs the extended battery 4.173 V Li-Ion 1850 mAh
which sits very stable at 4.173 V
info from BatteryWatch App, also Battery Indicator Pro
Sorry, I don't have the link handy, but somebody else on the board posted a detailed explanation as to why that is. It has to do with the way Lithium Ion Polymer batteries work. If they're at 100%, the cathode (or anode, I forget which) corrodes and the battery goes bad much more quickly. So our phone is designed to charge up to 100%, then stop charging. It will let the battery get down to somewhere in the 90's, then start charging again. It lengthens the life of the battery.
If you desperately need the 100%, you can turn off the phone, un-plug and then re-plug the phone into power. Then it will charge back up to 100%.
What I do if I'm going to be away from power for awhile is bring along an external battery pack. I bought a decent one from Best Buy for $50, and it's done a good job. I just ordered an 11,000mAH external battery (http://www.amazon.com/gp/product/B003ZBZ64Q/ref=oss_product) and a double-A charger (http://www.amazon.com/gp/product/B003M9Z5F6/ref=oss_product). That should do me when I'll be away from a plug for awhile...

[Q] Any disadvantages of frequent charging?

Are there any disadvantages to having the phone plugged in a frequently as possible (e.g. charging over night, car charging, charging while at work)? I have been favoring 897 leaks over 9000 roms mainly because of battery life. I have been a fan of Apex roms and now that A11 is out I want to give it a try but I know I won't get the same battery life as Illuminance. Could I damage my Captivate from frequent charging?
Now i could be wrong, but frequently charging *may* reduce the life of the battery....i believe every batter has a certain amount of "charging cycles" it can have before the battery begins to lose charge quicker...again, i could be wrong..
True, batteries do have a certain account of charge cycles, but a charge cycle is a 100% drain and back up again.
So down to 50 then charge, 75 charge, 75 charge, is only 1 full cycle.
So whether you wait to charge til it's dead enough to not run the phone (it actually shuts off before true 0% to save the life of the battery) or you grab some spare juice when you can, your battery should have about the same life span.

Ya this is true but I find I that I get much better battery life if I do a bump charge. Ive charged to 100% on the phone screen, turned off the phone, plugged the charger back in, and had it charge for another half hour until it hit 100%. So I dont know what it is about charging in that fashion that works for me but it really seems to help. I also am pretty good about cycling my battery 0-100 100-0 so that may help.

bump charging will kill battery life long term..
Also, be careful with car chargers. Some of them are designed to charge faster which will also shorten the over all life of the battery.
Lithium batteries don't like to be drained fully. The best time to charge is 30-40%. Also lithium doesn't like the "fast" charge. Basically be easy on the drain/charge/level and it will last longer.
The 1/2 hour you're talking about is because the last 5-10% takes the longest. You can actually charge from ~40%-80%+ very shortly due to the way Lithium works.
As I said above, the phone shuts off before the battery reaches 0%. You notice it still has enough power to run the charging animations even though its too dead to boot.
the phone also stops charging at 100% let drain to 95 and back up, to prevent overcharging.
both are to save the lifespan of the battery.
Discharging below three volts will cause damage. Charging over four point two volts will cause damage. Charging at a greater rate than one C will cause damage. One C is equal to the capacity of the cell. Our stockers at 1500mAh should not be charged at a rate greater than one point five amps. I believe the stock charger outputs 800mAh, or point eight amps. Any damage to the cell will definitely shorten life. The more you use a battery the faster it will die, true with any type. Hope this helps someone.

I don't really see this as a matter of choice. My phone dies daily, so I have to charge it daily; I have to bite whatever happens with it anyway. If it helps, I got my phone on launch and have been using the same battery through my warranty replacements. My battery maxes out at roughly 15 hours of moderate use, 20 of light use.
frequent charging reduce battery life so it is better to charge when ur battery is left with 15% or below and charge it completly

This is very true of Lithium ion batteries. They like to be kept topped up constantly. Not letting it go to 0% consantly helps. This is very different from NiMH or NiCd, where the "memory" effect requires you to completely discharge the battery before next charge.
The best way is to just put the phone on charger whenever you are not using it - if ever - just plug it in and let it sit till you use next time.....
FFS how many times must I say it? THE BATTERY NEVER REACHES 0%!!!
There is ALWAYS some amount of charge even when the phone won't come on.

Very true. If you discharge a lithium cell below three volts, you run the risk of it catching fire or exploding.
Should've mentioned earlier that as the battery degrades, it loses capacity. This is what causes them to seem they're not "lasting as long" or "draining faster".

Charging the x8

How should I charge the x8 or any li-Oh battery for that matter? What do you do?
Leave it until empty
Charge just before dying
Charge whenever I have the opportunity.
Wrong thread.
I charge it when it dies.

I charge my phone anytime! If battery has 70% and I know that I'll use it next day very much I always charge it to 100% !
yh
Yes i charge it whenever I can
Just when it dies
whenever it dies
I charge whenever it dies
Well, a little research :
Avoid fully discharging a lithium-ion battery! Unlike Ni-Cd batteries, lithium-ion batteries' life is shortened every time you fully discharge them. Instead, charge them when the battery meter shows one bar left. Lithium-ion batteries, like most rechargeable batteries, have a set number of charges in them.
I also just recharge whenever I think necessary.
i charge whenever i want

Great Thread
Hm, great thread..I charge my X8, when was 3% of battery..And always charge to 100%..
you should avoid letter a li-ion battery get below the 20% area as this damages the cells in the battery li-ion have no memory effect unlike ni-cad even ni-mh battery had no memory effect but they did need a big first charge
I Charge my battery, just before dying. :laugh:
i charging my x8 before it dies.
@Deftone and @ androidnerd2
our battery is lithium polymer not lithium ion.
so we can charge it anytime we want its life is not compromised.
and ya its true we should not use it till the end of its charge.
but our mobile takes care of it. it shuts down phone saving some charge in battery which is always needed otherwise battery wont even charge if voltage drops down to large extent..
Lithium batteries in general are better to be discharged as much as possible before charging.There are several rules for optimal charging like turning device off or not topping off the Ion based ones but in general dont charge them unless you know you ll need it and dont be afraid to let them dry before charging them again.There is no memory effect on Lithium batteries but there is a Life cycle that you can extend with less frequent charging.

Concerning the Nexus 5 battery, how do you recharge your device?

Hi guys, good afternoon, how are you?
As I was looking after the Nexus 5 and the battery life of the device began to get discussed, I was unaware of the fact that nowadays we can just charge the device however we like, using Lithium-ion polymer batteries, different from the past, when a full recharge was recommended for the battery performance not get affected.
Considering that, for some users the battery life shouldn't be a concern, mainly for those who have a power outlet nearby, making an option to recharge it at any % level before getting it to fully recharge during the night.
I'd like to know from you guys: how do you recharge your devices? Do you wait for it to drain every % of the battery before recharging it or just plug it on the power outlet whenever needed?
Also, do you guys believe that recharging it at any % level does not affect battery performance?
Thanks a lot!
Modern batteries have a finite number of charging cycles before they being to lose performance. Generally speaking, 100%-0% is one discharge cycle, so if you want to maximize battery longevity you should do your best to minimize the number of discharge cycles you subject the battery to. It is not strictly speaking a direct relationship, but the battery should last longer if you charge it when it reaches 50% as opposed to 0% (that would qualify as "half" a discharge cycle).
When I'm using my device heavily and I have access to an outlet, I leave it plugged in. That saves on discharge cycles. Also, when I am sitting at my desk at work I generally keep it plugged in.
The following link is an excellent source of information regarding batteries:
http://batteryuniversity.com/learn/
right now with my current phone i'll usually just top it off after work from a wall outlet, or top it off in the morning when i wake up and get ready for work. i also have a usb cable at work to top off whenever needed throughout the day. i try to keep the battery over 50% most of the time, just because, but i rarely leave it plugged in throughout the entire night, and this is even with running sleep tracking apps. i imagine battery use/charging will be the same with the nexus 5 -- topping off in the morning while getting ready for work, maybe charge a bit while at work via usb cable, and topping off after work via wall outlet.
i guess i charge my battery in intervals throughout the day, instead of the daily 8 hour overnight charge. however, i usually keep it at least half full
Plug it in at night before I go to sleep.
If i'm using it heavily and it gets below 50%, I'll plug it in.
Some days at the office I'll plug it in about an hour before I leave so it'll be almost 100% after work.
If i'm going somewhere and feel I may run the battery down before I get home, I'll carry my portable charger with me (Anker 5600mAh).

Wouldn't heavy usage while its charging put too much heat on the battery? Which is worse for it then worrying about charge cycles?

It depends whether/how much heat is generated during heavy usage. On my N7 while browsing the net or watching videos the heat is non-existent. Certain games cause more heat than others. If the device starts to become "hot" then yeah, keeping it plugged in will only exacerbate the problem.
Also, having a case on the device can increase heat soak.
It depends on the situation.
You are right though that heat is the enemy when it comes to batteries. About an hour in my back-back on a beach on Oahu killed my GNex battery, and it was in the shade too.
I plug mine into a wall charger or my laptop...
At the end of the day though, if you don't bake or freeze your phone, the battery should last at least a couple of years without losing too much capacity I think.
The battery longevity discussion with mobile devices is similar to the oil change debate in automotive circles. Some people swear by certain brands and oil change intervals, whilst others just buy what is on sale and change the oil when the car tells them too. It probably makes very little difference in the end.

To OP:
Today's lithium ion batteries are way better than what they were 10 years ago. As posted above, go to battery university and learn all about it. My advice? Don't worry about special ways to charge your phone. You'll break, sell, or permanently store this phone long before your battery gives out due to charge cycles.

This!
Once upon a time I used to wait till my phone drained to 0-5% before I charged it. But I quickly realized that doing so turned my battery into trash.
So now with my 2 latest phones I usually charge it when they are at 30-40% or higher if possible and not only do I get excellent battery time but also its lifespan & performance doesn't deteriorate over time.

The only advice you need: DO NOT FULLY DISCHARGE LI-ION BATTERIES. These aren't NiCads, you do not need to power-cycle them periodically.
For best Li-ion life, try and avoid discharging below 20% or above 80%. Manufacturers will often add some 'headroom' to the 100% level (so that a battery that reads 100% is actually only charged to 80%-90% of capacity) in order to maximise longevity. within that range, charging and discharing will have little effect on battery life. charge and discharge rates do have an effect, but again ythe battery controller will limit these to prevent damage to the battery, so this is not something you need to worry about yourself.
Keep the battery topped up and avoid discharging it completely. Anything else is hocus-pocus or incorrect advice for the wrong battery chemistry.
i replace my phone once a year so i dont bother with saving the battery etc.. ive never had any measurable degradation to the battery the way i charge in less than a year. I usually charge it from what ever % its at to full. Most of the day at work it stays on my wireless charger, but it stops charging it after its full.
Thanks everyone for the feedback this far, in just a couple of minutes I already learned a lot.
Please let's continue the talk and vote if you can!
Thanks again.
On the charger before reaching 10%, around 20% or higher if it's possible.
