while on charger when the battery is reaching 97% , turn on/off/ the phone
multiple times , each time taking a 2 mins break u will notice the charging takes longer and the percentage is always stuck at 97% - 99%...
another form of bump charging for wp7..basically the phone will take longer to cut off charging at 100%
post yr results here if u saw improved battery life
you will find this quickly damages the long term battery life of your battery
Well that isn't so bad as batteries aren't expensive anymore. Just 12€ or so.
this would probably work for any phone not just HTC but you are basically tricking the phone into over charging the battery which weakens the lifespan of the battery, all for a few extra minutes of battery life, not worth it.
Yea, this is terrible, destructive, downright negligent advice.
Yes, not good. I work with battery chargers and Li battery characteristics and you will actually age and get less capability very shorty doing this so you won't get those extra charge lengths for long (you do this maybe 20 times and you will in worse shape after that than someone just doing normal charge).

Hah, this coming from the guy that advocated doing that.
u understand yr cause of concern....this will not wear out the battery faster...unless batteries that u use do not have rapid discharge capabilities eg. Iphone poly battery.
In this case it will wear out the battery faster
basically the battery wears out the same rate as all other batteries...
the cells degradation occurs each time u charge...
and modern batteries do not overcharge...some like HTC batteries will discharge rapidly to 80%
basically u are just charging the remainder of the cells
Quote me where I advocated doing that.
Please do a post search on me and you'll see that we've had this discussion in the Vibrant forums already, where I stated it was dangrous.
What I do advocate is keeping your phone on a charger whenever possible (bump charging).
I do not advocate tricking the phone into overcharging. No one wants a battery to blow up in their face, you know...
Or maybe you're confusing a confirmation of that working with an advocation that it's okay to do it? In that case, your school district obviously failed. It has nothing to do with what I stated on these forums or otherwise.

The issue doesn't come from fear of wearing the battery down. It comes from fear of a device blowing up or catching fire on someone who is overcharging it. There is enough evidence even on youtube of batteries going haywire. This is a risky tactic to achieve basically no noticeable increase in battery life.
The HD7 in a high 3G coverage are (full bars, 3+ Mbps download speeds) gets ~4 hours of battery life under heavy use (mostly browsing, reading Pulse Reader Articles, and checking Social Networks now and then - no Music or video - so really it's only heavy in the fact that the phone didn't sleep a lot, should be called more moderate if anything... Phone shows 67% battery left with 2 hours projected uptime). Overcharging your battery won't change that terrible battery life into good battery life. It'll only make it 5 minutes less terrible.

they can only blow up by removing their circuit protection
If you say so
Batteries still overheat, catch fire, and in rare cases blow up. Overcharging them is risky. Yes, it's rare, but would you want to be that 1 in 10,000 case where it does do that, in your pocket or something?

1.) This will wear out battery faster, why? You are fooling the sensor to charge the battery more.
2.) You can overcharge batteries, don´t know where you found out you can´t. The only good thing is, that the modern phones cut out charing when battery is full and is running on charger (to keed battery charged).
3.) My battery is not rapidly discharged to 80%, I charge it up 100%, and it stays there, when your battery quickly discharges to 80%, that´s your problem from experimenting with charging.
Again - STOP TELLING PEOPLE TO KILL THEIR BATTERIES, I told you numerous times, you always act like you invented something, you didn´t, modern batteries use more advanced techniques to help them prevent from being damaged, overcharged, deeply discharged, etc. So stop telling people how to fool these sensor and stress the battery.
Thank you
Hey guys,
I wouldn't recommend this advice as well.
As for me, I bought a second battery 1600mAh.
I use this battery as my primary battery, now I get 30-40% more time on my HTC HD7, and actually can go a whole day with 2G only. While before the phone dies before the end of the day.
While my original battery I keep fully charged sleeping in my wallet, so if the 1600mAh is fully depleted and I'm away from a charging station, I quickly replace and resume working on my phone. This method gets me through a whole day of work+games+social.
I don't remember the price of the 1600 battery but it costed me 10-15 Euros I think.
I believe this is most practical than carrying an attached battery to your phone which results in a gigantic phone in your hands. Or overcharging the OEM battery and probability of having it blow up.
What do you think guys?

does it really last longer???
Wanting more battery life and having reading a few positive reviews about the Gold 3500, I got one from Amazon (UK). The numbers 3500 vs 2500 mah indicate I should get around 40% extra battery life compared to stock but having played with RC cars and helicopters running LiPo packs I know that pack ratings aren't everything.
Actual battery capacity depends on the discharge rate, the more juice you pull the less the effective battery capacity you get with a lot of energy wasted in heat due to internal battery resistance. Fact of life with batteries of all chemistry.
My original battery is about 6 months old now, charged daily from anywhere between 0-50% remaining. In day to day use the Gold does seem to last longer based on my 6 months experience with the original battery but how much better is it?
I charged the batteries in my phone and turned the phone off once it hit 100% but kept the charger on as it seemed to charge for a bit longer.
Using my RC battery charger, I used the discharge function setting the low voltage cut off to 3V (standard for lithium batteries) and set the discharge rate at a constant 300 mah. Using a constant discharge rate may not be realistic but it does allow for a fair comparison, keep in mind that our phones power usage jumps up and down depending on use.
Results
-----------
6 month old stock battery rated at 2500 mah = 2364 mah (which is what I would expect from a battery with 180 cycles on it)
Brand new Gold 3500 rated at 3500 mah = 2524 mah (a bit disappointing but at least as good as a new stock battery)
Now the discharge rate can make a big difference to effective battery capacity, it might be that the 3500 mah rating on the Gold batteries was determined using a very low discharge rate or they discharged it to below 3V.....or its just a gold wrapper over a stock battery
Interesting to note that the stock Sammy battery is pretty true to its rated capacity, so the perceived increase in battery capacity I experienced with the Gold battery is probably just the difference between a 6 month old battery and a new one.
Oh well, at least I have a spare battery now and didn't pay a fortune for the Gold. The Gold does seem to last a bit longer than the 6 month old stock on so I am happy enough with it.
Notes:
Gold battery had been in use for 2 weeks to run it in
Only one discharge cycle was performed
Could be that I have a dud battery, you results may differ
In real day to day use the discharge properties of the Gold may result in a higher 'effective' capacity
Solar flares are the source of all coding errors
Fairies do live at the end of your garden :cyclops:
It's a shame i've read this post only two days after buying me one of those. Anyway, even if it won't last longer, i'd still have a spare battery right? So everything is not lost
nope, its a shame they rate it 3500mah if this is the case for all.
Mignon, maybe your can get a replacement from thrm and test again. Especially if you have a dud.
Do notice I notoce a significant increase in battery life after charging it past 100%. Probably placebo, I dont know.
Don't think I have a dud, in my experience lion batteries either work or don't. It's not a crap battery, it's just as good as stock but doesn't match the advertised 3500 mah rating.
And it's shiny gold so things aren't that bad

Well that sucks.....haha...i order a gold a week ago.....it should be here soon.....
I got 3500mah gold battery. I review it.
My rom is ultimate rom v5.1, and my stock battery was 11 months old.
Screen on time was always less than 4 hours.
Yesterday I got the gold battery, and I used it up to 1% without first charge, then I charged it 12 hours to initilize the battery.
So unpluged the charge, and tested it as the same usage. I always downclocked to 1000MHz, wifi on, no use 3g data, brightness is zero, bluetooth and gps is off. I downloaded 15 files and apps today, listened to music, did multi windows function, and almost used web browsing.
Now my battery is just 1%. Screen on time is over 5 and half hours. Obviously the battery was improved.
If official JB are released, the battery will be improved more.
But this is not made in Japan. This is made in China because Japanese is so strange on package.
Some of Chinese battery are so dangerous and may be fake, but this gold battery is good one.

I dropped my stock and it works perfectly till 55% then it dies. Gonna throw it away soon. So some of the cells could be damaged. Its not either they work or dont m8.
@Mingnon thanks for your effortful tests.
@eeynjae, what are all apps spreading around those icons in your notification bar ?
I am pretty sure most mobile 3.7v phone batteries are single cell, only the mugen styled battery extender jobs that require a different back cover run two cells in parallel.
Remaining capacity is usually just a function of cell voltage so it's strange that it should just tank at 55%. Battery protection circuits generally prevent discharge past 3.0 volts so not sure what it's going on there.
Either way it sounds like you need a new battery, wouldn't risk recharging a damaged cell...

yeah its strange. Stuff started to happen at 50, whrn restarting bat percentage dropped to 10-15%. Without restartingbit would go down normally in beginning. Now after using it some time and dropping it its 55%.
Its definitely it either works or doesnt.
Anyway I dont think it's single cell.
i have the same battery bought it a few months back i'am very satisfied....
it's not a 40% extra time even framework it designed to work with less voltage since after using it below 15% i notice always fake meter value, when you keep your phone asleep for half an hour you will notice an increase in percentage. not accurate but runs fine, its a spare and a great replacement i dont care if it's slightly powerful than stock at least its the same size for 4 extra hours.. i never needed to change case nor a cover of anything its great
Sorry for my off-topic question, but i see in this topic there are advised people recently i bought a noname car charger for my Note, (specs: output 5.5V DC, 800mAh) - is this charger good for the Note or it would damage it? (i read somewhere that the original car charger's output is 5V... this difference of 0.5V has any importance?) Thanks.

Thanks for your time and efforts - your results are similar to my amateurish measurements performed twice and reported on the other 3500 battery thread. Having no device to test the actual capacity, I just used the continuous video playback in plane mode with minimal backlight. The time to full discharge was almost identical in both cases.

It won't damage your phone, but if you are going to use it as a gps while charging, it will probably keep dranig the battery, 800mah is not enough to charge it while screen is on and gps is running

Why is that?
After i've received mine, i've never ran out of battery during my day. Definitively improved the usage of my phone.
I bought this exact battery on eBay:
http://www.ebay.com/itm/4800mAh-Ext...US_Rechargeable_Batteries&hash=item51a976ade9
It said it only worked with the i9300 Galaxy SIII in the ad, but when I got it, it fit fine into my SCH-I535. I am doing the initial charge on it now. Only problem is not having a pebble blue case but oh well
it seems to be charging much more slowly than the OEM battery but I guess that's to be expected with the higher capacity.
Ballsy. Def post some screen shots. Wanna see how this turns out.
At this point, my phone is just one big tweak.
Seems like a good price. Would love to see some screen shots of battery usage if at all possible.
I bought the one from gorilla gadgets.com that thing is the best $20 I've ever spent. Bought it in September and I still get over 6 hours screen time with almost every charge. You should check it out

You may want to re-read the article you linked to. From the link.
Rather, to condition a new Li-ion battery, fully charge it; it should be allowed to charge for 7-8 hours on the first, initial charge. In other words, when you get your new cell phone – and it has a Li-ion battery – allow it to charge for 7-8 hours even if the cell phone claims to be fully charged. (It is preferable to use outlet charger vs car charger or USB charging via computer because of the voltage difference.) After that, there is no reconditioning necessary for Li-ion batteries since they don’t suffer from the “memory effect”. However, be sure to avoid fully draining/discharging the Li-ion battery as much as possible; every time a Li-ion battery is fully discharged, it loses battery power and life
Do you find that the battery drops very quickly from 100% to 90%? And then hovers at 90 for a much longer time?

It'll work good for a while, but eventually the battery will last less and less longer, that's been my experience with cheap batteries, but even when the battery does "settle in" and not perform as well as it did in the beginning, it still performs better than stock (In times of battery life, couldn't comment on how safe it is and if it's efficient)

I can see that. After all every battery has a certain amount of battery cycles it can go through. But for me personally that wouldn't be a problem, because if You always cycle through several batteries, then even those very cheap batteries will last the lifetime of the phne.
As well as being an avid android user, I have been flying electric RC planes for years.
I have seen very expensive (not made in China) lipo batteries of 2200 mah explode
or create a long flash fire. I would like to ask some of the gurus on this forum what
their thoughts on the safety of the Zerolemon 7000mah battery. I recently received it,
and love the long life and even the size (but not weight) of my GS3 now. I am quite
concerned that the battery is basically 3 regular batteries slapped together in China.
I know enough about lipo batteries that a dropped battery, a battery left in the car, sun,
or hot pocket, or even just an old battery can spontaneously combust. I would have
felt much better if it was actually one battery, but since it is 3 ran together in series,
even if one is faulty or shorts, it will set up an instant fire bomb. From what I have
seen with my RC batteries, you would be severly injured if the phone was on the desk
by you or charging, and if it was in your pocket you would surely be killed or permanantly
injured and disfigured. I don't want to sound like an alarmist, but my vast experience
with lipo batteries has taught me to be very cautious, even storing the large ones.
Every once in a while you will see or hear of an iphone or android phone blow up, and
luckily they were on the passengers car seat or a picnic table, but even with a 2100 mah
battery the damage is devastating. Any serious comments or discussion of this safety
issue would be appreciated.

There are tons of them spontaneously bursting into flames. Just Google it, tons and tons of threads made every day to. They narrowed down the fires last summer in Australia to be caused by one last year.
With that being said I'll take yours from you if you don't want it. Oh and all other batteries you own since they all pose the same risk.
I am pretty certain they are run in parallel, and with built in charging circuits I think they are just as safe or dangerous as any other after market battery. I have flown my brushless lipo E-Stater for years and even shorted one of the batteries (only for a few seconds), it swelled but never spontaneously conbusted. My RC boat is lipo too and no probs there, nor with either is my Cox foamies.

Thanks for a sensible reply. And I spoke to an engineer friend and he said they were run in parallel, he said in the rare event one ignites in your pocket you are just as screwed with one than with three. I kind of disagree since setting off 3 2100mah firebombs in your pocket would certainly do more damage than setting off one 2100mah, and the Zerolemon is just 3 2100mah batteries slapped together in parallel, and if one goes off they all do, chain reaction.
My friend has also been flying RC for 30 years and last week was his first lipo fire. We both have had many puffed batteries,
but he was flying a new Parkzone Corsair and it just burst into flames and smoke mid air. He had a very expensive but old
battery in it, but Parkzone is sending him all replacement parts for free, so I suspect they know they had a bad ESC in a
batch of them. Then again it could have just been that old battery, we will never know.
My thought process is this. That rc is using the battery at a much faster rate than the phone. So I think most regular use discharge explosions are flukes. Maybe 15 phones blow up a year but how many phones are being used every day. It's pretty simple; If your phone starts getting extremely hot, take the battery out and let it cool off, don't keep your phone in direct sunlight, and always be mindful of your phone's temperature even in your pocket. As far as explosions while charging always make sure you're using a compatible adapter with the correct voltage and use your phone as little as possible.
Sent from my SAMSUNG-SGH-T999 using Tapatalk 2
Yes the RC does use the battery at a far faster rate, but they are designed for that.
RC batteries and Cell Phones are both dropped all the time, cell phones much more.
This dropping can damage, vibrate, or short the battery and even if not first apparent,
this damaged battery can combust right away or later after more wear. That is what
I am concerned about. The zerolemon is 3 batteries packed together, and heavy, when
you drop your GS3 the battery is the whole back and takes all the damage (unless
dropped on the glass facing). The standard battery is embedded in the phone and is
therefore protected from drops.

concerned that the battery is basically 3 regular batteries slapped together in China.
I know enough about lipo batteries that a dropped battery, a battery left in the car, sun,
or hot pocket, or even just an old battery can spontaneously combust. I would have
felt much better if it was actually one battery, but since it is 3 ran together in series,
even if one is faulty or shorts, it will set up an instant fire bomb. From what I have
seen with my RC batteries, you would be severly injured if the phone was on the desk
by you or charging, and if it was in your pocket you would surely be killed or permanantly
injured and disfigured. I don't want to sound like an alarmist, but my vast experience
with lipo batteries has taught me to be very cautious, even storing the large ones.
Every once in a while you will see or hear of an iphone or android phone blow up, and
luckily they were on the passengers car seat or a picnic table, but even with a 2100 mah
battery the damage is devastating. Any serious comments or discussion of this safety
issue would be appreciated.

There is the possibility of ANY battery exploding. First of lets get the terms correct. Per an E-Mail from ZeroLemon the batteries are not Lithium polymer (lipo) they are Lithium Ion. They do have the built in circuits to prevent overcharging and to regulate the charge going in. Now a Phone does not get the abuse that a RC Car gets. The Phone is not charged as fast as the battery for an RC Car. When it come to the 2 RC Car or Phone, Apples and Oranges. I don't see it being a problem.

I am talking about RC airplanes that do not get any abuse (unless crashed and you throw it away), not RC cars.
Cell phones are dropped all the time.
This dropping can damage, vibrate, or short the battery and even if not first apparent,
this damaged battery can combust right away or later after more wear. That is what
I am concerned about. The zerolemon is 3 batteries packed together, and heavy, when
you drop your GS3 the battery is the whole back and takes all the damage (unless
dropped on the glass facing). The standard battery is embedded in the phone and is
therefore protected from drops.
All batteries will always be at risk to explode. That being said the chances of your phone exploding and seriously injuring or killing you is probably lower than you getting hit by lightening so, you can live in fear or take your very good chances.
If this has scared anyone away from using their battery I'd be more than willing to buy it from you.

Hey people,
New to wireless charging here, my girlfriend just bought a wireless charger for my birthday. Just one question, when you are charging and you need to use the phone, should I pick it up or leave it there and try to use? I mean, if I keep picking it up to use, wouldn't the constant charging/stopping damage the battery? Please help me out!
Thank you!

No, it's fine. Pick it up as many times as you want. I have different wireless pads scattered throughout my house, office and car, that it will not "hurt" it.
It's probably fine. But if by constant you mean literally every 5 seconds then maybe not.
Also there's a xposed mod to disable the sound every time you put it on the pad if they annoy you too constantly.
BTW it'd be great if I had a techy girlfriend
thanks for the comments guys

uh yeah, no thanks, charge cycles take their toll on the battery.
people like this are why batteries have to be replaced.
Personally, it's only $15 to do yourself, so not a big deal. Just don't tell people it's fine. Get a degree in Electrical Engineering then tell me it's fine

AFAIK li-ion batteries does not suffer from any memory effect and they even last longer when kept charged. Battery charge cycles are still there as an indicator of the goodness of the battery from the manufacturer but they are related to a full cycle (eg how much current passes through the battery) but smaller charging cycles shouldn't be counted as full.

What's the best charger for you guys ? I mean what's the more efficient charger, the official from the Google play or others ?

Well I had my phone since released and before that used my Nexus 4 and used wireless chargers since then. You mean to tell me we all need EE degrees to use/charge our phones?
Just use the pads no need to "worry" about the battery. In some instances batteries will need replacement, but many replace their devices well before you see an issue.
I don't want to go to e-war about batteries. I am just going by personal experience. I have my N4 still, which my wife uses and still uses charging pad still no issues there either.

Could you provide some references for our edification? I admit I'm not the most knowledgeable on the subject but my understanding is that charge cycling is bad at or near full charge. I don't know that this a problem at lower charge levels (let's say <90%).
I don't have an EE degree but from what I understand newer batteries cycles are a full charge from 0-100. I read something on apples' website explaining this. So charging it twice from 50-100 would be one cycle.

noppppppeeeeeeee, left at full charge lose 20% of capacity after 1 year. see:

You might be right about the charge cycles, as most things seem to relate to amount of power transferred through the battery, and not 'depth of discharge" but honestly many people I've met who plug their phones in all the time to top up, end up having to get the battery replaced after a year. Apple product, ok no problem they do it free for like 2 years; but I've done nothing but run my batteries all the way down every time and slowcharge every night on USB-500mA (gentler current, kinder to battery, cooler temps, and even a slightly more thorough charge) (just 5% POSSIBLY 10% it's hard to say...probably 5%...I guess I should test this)

EE to charge? No, I'm just saying you might want to think twice before picking up 20 times a day from the pad. Better to get MightyText for when you're at your PC/work to text with.
the google charging pad IS better I would have less issues charging on one of those. However, I'm a cheapie, and use $10 chargers, which heat my phone usually to 40C for a full 0%-100% charge. Not best, but I have resigned myself to the reality of potentially replacing the battery in 18 months if I want the convenience of charging pads everywhere. You might wish to think this way as well. Also, after 18 months, maybe you could just charge it at every opportunity (at that point, who cares, you only need it for another 18 months probably) and that would be enough.

All I know is since 1998 I charge my phones to 100% as often as I can find a charging device. I am the only one on my family plan of 5(the others run battery down daily to~30% or more) that doesn't replace their battery before their next upgrade. So my motto is *Top up every chance you get*.

Bought this for just 8,33 euro shipped (9.99 $) and works like a charm! :good:

I don't think we need a degree in EE... All you need to know about batteries is in this place: http://batteryuniversity.com/
Go a take a look at let those "dogmas" change.
Peace.

Not sure if it makes a difference but nexus 5 uses newer li-po batteries not li-ion.
