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?

NO, NO, NO. PLEASE stop spreading bad information. This will HARM the battery, and will have 0 benefit. The only "benefit" you can get from this is that the battery meter on the phone's firmware will be calibrated to show a more correct remaining %. You can achieve the same by charging the phone 100% (overnight) going to clockwork recovery and selecting 'wipe battery stats'. Calibrated or not, the battery will last the same, regardless of what % left its showing.
Again for posterity, REPEATED DISCHARGING OF LI-ION BELOW 20% IS BAD FOR THE BATTERY, IT'S PHYSICALLY IMPOSSIBLE FOR IT TO GET BETTER.
I am having a similar issue with a battery that I ordered off of ebay. It's 3500mah.
When I plug it in it will turn off and get stuck in a boot loop on the vibrant screen, but if it is off then it won't turn on at all when plugged in. It has been plugged in for 9 hours so far and it doesn't even show the charging animation or anything.
Normal? Or is the battery defective?
Thanks.
Ok. After charging it overnight and still nothing, I'm going to assume its broken. Thanks.

I am not so sure about your information. This is what DHGate, a wholesale Chinese online store wrote about the 3000mah battery for Galaxy S [not MUGGEN!]
How to use a new battery:
1. First when you received the battery,. you need to release the power in the battery, just put it into your phone without charging.
2. After the battery power is out, please charge it about 12 hours in first three times.
3. So the battery will be actived. So you can just charge it about 5-7 hours when use in the further.

No controversies at all. Your info from the link is outright wrong.
Mannymal is correct on this one.
I also have this battery. By the time I got it, Team Whiskeys roms had gotten good enough to where I didn't need an extended battery for day to day use (stock battery usually has 30-40% when i go to bed), but I do use it when I travel, so I don't have to worry about using it like crazy. The battery lasts a long time, probably like 2 or 3 days if I actually tried to drain it, at least. And it's definitely adds bulk, but it's reasonably well made and feels sturdy.
My only complaint is that I sometimes cover the speaker with my finger when I want to silence it real quick, and it doesn't work with this because the cover's so far from the speaker. But that's just my weird thing.
Also, yeah, don't kill your battery. No es bueno.

Just got it in the mail - had pre-ordered it from Mobile Fun about two weeks ago.
Someone else posted pics already, but couldn't find the thread - here are my own.
Note, the case acts as a battery charger, and starts delivery electricity as soon as you put the phone in. There is no switch on it. I'll have to see in the coming days, but it looks like it's necessary to only put the pack on when you need it.
Things I fear but may be unfounded:
it won't be practical to leave the case on at all times
need an extra charger to charge them seperatly and efficiently
I hope I'm wrong, and hope I can just keep it on at all times, and charge both the battery and phone at the same time using one charger.
Thanks to Eiraku posting in this thread, I was able to find the original thread for this battery pack:
http://forum.xda-developers.com/showthread.php?t=1110441
Mods please feel free to merge subjects.
Here are more pics
Isnt it a bit harmful to always have the battery at 100% charge level and even have trickle charge, they should have implemented a switch or at least some control mechanism to have it start charging only at around 50-80%
I think you're right, and indeed, the case start charging the phone even if the phone's battery is full.
From the manual:
"When not in use, remove your phone from the power pack."
Kinda of a let down. But I'm still happy to have it for my asian trip at the end of the week - electricity will sometimes be a luxury.
The purpose of this case is kinda moot if it does not have a switch and cant be kept in use.
Thanxs for the pics...I ordered this case from expansys a month ago and am still waiting on it to ship. Looks great.

There IS no such button. Only the battery tester button (which is useless).
Cost cutting, Samsung? You delayed the battery pack to remove that freaking power toggle?
Personally I can't wait for PowerSkin to come up with something better (OR that urban legend official 2000mah internal extended battery with new cover to come out). But as of rite now, I'll take what I can get.
To OP: thanks for the nice pics. They're much better than mine anyway. And welcome to the club!
There is indeed a button as indicated on the pic you have there, but on mine, it doesn't quite look like that. There is no marking on it or next to it - it's a simple push button which function is to indicate battery level. When you push it, the battery indicator will light up green, blue or red according to its energy level.
The pic you have may be a prototype or maybe a different version other people are going to get?
Without power toggle
I will cancel the order
Guys,
Surely just because there is more power available behind the standard battery, doesn't mean the phone will suddenly start drawing more power from it?. A car doesn't consume more petrol when the tank is full... how would this be any different to putting a ...say 2000 mAH battery (if it becomes available) instead of the original OEM battery??..
More mAH added by the sleeve should give extra run time...
Riz
I'm no electrician, but I like the full tank analogy.
Imagine the tank is full, but let's say I keep pouring fuel in the tank while the engine is running ... kinda of a waste as the extra fuel will spill - not to mention the danger.
So the question here, if the energy or extra energy delivered by the battery isn't being consumed, is it wasted? Is there danger if there is "spillage" in the form of heat? This phone can already get incredibly hot it you use it as a GPS for an extended period of time.
I'm still concerned about what the manual says about removing the pack when unused.
Actually, I have all confidence that this is a "smart" charger, in the sense that it will only top up the internal battery as necessary.
Using it as an "extender", I have no issues getting 3-4h extra on really heavy, constant screen on 3g surfing. It didn't even get hot at all, so power was NOT needlessly drained.
As a "charger", I got from 6% to about 42% from a fully charged extpack. In this config, the case did get quite warm, which indicated that it was quickly expending its reserves to charge the SGS2.
For a 1300-ish mah pack, this is more then consistant performance in my book, from my experinces from owning multiple iPhone 4 batt cases.
Only issue is with the lack of power toggle, there's much less flexibility allowed. You can't choose to keep the extpack as an emergency reserve UNLESS you take it out.
Also, it only takes in 700ma (the Samsung charger is rated at 750) and gives out 650ma, which means that in the event that you are charging a fully depleted extpack and say a 50% power left SGS2, the charging of the extpack will take FOREVER (phone first, then case).
But charging the SGS2 takes forever to begin with, so...
I'm no electrician myself...
But... about the car engine.... there are fuel governor controllers which only allow enough fuel as is needed to enter the combustion chamber...
but.... we talk of batteries... the way electrons work.... my understanding is...
flow of electrons is decided by the potential differnece available for them to travel across.. the higher the potential difference... the more electrons would flow...
So, lets say... the SGS2 has a power consumption of 100 milli-amps (based on whatver the volgtae rating is).... a 100 mah battery would run it for 1 hour... a 500 mah battery would run it for 5 and so on....
Adding a battery in parallel.... would not increase the power consumption from the original spec'd power requirement of 100 milli-amps... it'll just increase the total amperes available to run the device... so.... more ampere-hours available... hence longer hours available to run the phone
Quite simply, it is similar to leaving your phone connected to the charger... I'm sure most of do this every night for the duration of the night....
leave the phone connected to the charger... i.e.
Ars Technica has a good article on batteries. It basically says this thing should have a power button!
http://arstechnica.com/gadgets/news...-is-the-best-way-to-use-an-li-ion-battery.ars
"On the other end of the spectrum, keeping a Li-ion battery fully charged is not good for it either. This isn't because Li-ion batteries can get "overcharged" (something that people used to worry about in The Olden Days of portable computers), but a Li-ion battery that doesn't get used will suffer from capacity loss, meaning that it won't be able to hold as much charge and power your gadgets for as long. Extremely shallow discharges of only a couple percent are also not enough to keep a Li-ion battery in practice, so if you're going to pull the plug, let the battery run down for a little bit. "
I believe that the phone, like the iphone, and most laptops, don't fully throttle their devices on battery. So maybe when it's plugged in it would use more power thinking that it's tethered into the wall. I had that issue with my iPhone 4. I had a battery case for it. The phone itself could last me say, 6 hours on its 1400 mah battery. When I put the 2000 mah battery back on it, before the battery pack died, was only 5 hours. So my phone consumed 2000 mah in 5 hours, while on the internal (smaller battery) it consumed it within 6 hours. Hmm... That's not right. So, then I investigated it and while plugged in the phone went into "performance mode"
Is that at all possible on THIS phone as well? hehe.
I'm not big on the whole battery switch, so, I'm skipping this case. I wrote power skin and let's see if they release one for the SGSII. I'd love it if they did

There's also the fact that a battery directly wired to the device will always perform better per mah vs an externally mounted battery. Heat loss through the external connector, yada yada.
If you're afraid of "performance mode" (which I also think some phones have), just use SetCPU to override it, like I do.
I'm hoping PowerSkin comes up with something soon too - as a case, the ExtPack has really crappy all round protection, especially on the front (getting the SGP Glas protector because of this).
i'd go for the case only without the battery.... it looks quite dangerous...
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

Quick question to people reading, to cycle the battery properly when you get it, you simple charge it to full in your phone, and then discharge it to zero percent. That's once cycle correct? This article I found said that you do that 4-6 times. Is that the correct amount of times?

here's one I took a few days ago. This battery seems to work better the harder you work it, kinda backwards of what you might think but hey oh well.

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?

Thanks for the heads up on that. For some reason, I didn't even see the Li-Ion section, and the parts that I mentioned came from the Nickel-Cadmium section
No I don't think the NFC works, what do you expect for $9.86 shipped from China?
(buy it now price with free shipping: http://www.ebay.com/itm/4800mAh-Ext...214&pid=100011&prg=1005&rk=2&sd=350739453463&)
Any more Screenshots please? I'm mostly interested in Screen on time.
Have other people also bought this battery and can share their impression?
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.
What's the best method? Drain to 0, charge to 100 a couple of times? Or charge to 100, turn off, charge to 100, and repeat? I've read some crazy stuff all over xda.
Edit:
Read some more stuff. Bump-charging and constant re-charging (preferred over single deep-charging) were mentioned as good for Lithium ion batteries, which I assumed we had. (Can someone confirm?)
Still would like your opinions!
Bump charging is in fact not good for the battery. It will stress the battery. Also no conditioning is needed with lithium cells. So just use and recharge like normal. There is no break in period. Also I know alot of people swear by deleting battery stats. This is not needed nor does it even do anything. All it does is wipe a log file. The file isnt used for anything other than telling you what has been using battery when you go to your setting and click battery. Google has even confirmed this. I will say this though. A few months to a year from now, if you still have this phone. If you notice severely decreased battery life. Take out your battery. Put it on a flat surface and spin it. If it spins the battery is bloating and should be replaced.

Avoid heat
Heat is the enemy of your battery.
In addition to what patrao_n recommends, I'd add removing the phone from any case you have it in before charging it overnight.
I love my cheap $5 TPU case, but it does act as an insulator and make the phone retain heat from charging and heavy use, especially when using 4G in a low signal area.
Yeah, I've noticed that it drains faster when I leave it on a table out in the sun as opposed to my pocket. No case for me.
So no conditioning needed at all? That's cool. Thanks guys
Well you have to be more specific regarding batteries. Whether it's the OEM battery or an extended battery like QCell. For the stock battery you don't really need to do anything besides the initial 8 hour undisturbed charge. QCell has it's own specific instructions that really don't go with the rules of lithium batteries but it works. Although for all batteries it's recommended to not let it fall under 20% cause killing a battery completely is really bad for it's longevity. So pretty much you don't need to condition anything unless you buy an extended battery and in that case follow the manufacturer's instructions to the letter.
Phone totally goes black/dies when battery is 21% down to 10%. does this just mean the battery I have is bad? What replacement battery is best? I've read Anker makes a good set with charger. Thanks.
Samsung SDI batteries are the only batteries I've known to do this. When screen goes black, that should be a shutdown. Do you plug in your charger at that time? Mine actually actually showed 0%.
It's inconvenient for a battery to shutdown unexpectedly, while showing capacity remaining. I always replace Samsung OEM batteries with another brand. I found one that I liked so l went to Amazon and bought a second plus external charger from same brand. If looking at another alternative, just search MPJ and read the reviews. The battery and wall charger were on sale last week, maybe still.
If you're considering upgrading to sealed battery in unibody phone, you should consider the care required for such a phone to get battery to last. Sealed batteries are actually very similar in capability and ratings; no leap in tech but apparent shortcoming evident in Note7 embarrassment. Fast charging produces heat and steals life from battery's endurance down the road. Studies have shown since lithium batteries have no memory that you're actually prolonging the battery by slow charging without load or minimum load and bump charging rather than cycling battery to near 0% then back to 100%. Manufacturers don't tell you that because they prefer you wear your battery down in less than a year's time and consider another phone purchase.
Maybe Samsung would be better off today if consumers were more aware of how to prolong lithium batteries?
If you want your battery to last two years, bump charge it after 25% used as much as possible; it shouldn't even matter if you bump charge it 3x per day. Avoid fast charging and heat cycles. IOW, try not to use it while charging; the cycles should be short anyway.
Or, if you prefer to abuse a removable battery like the Note 4 and care less, pay about $15 and just replace the battery every year. 500 full cycles is all these batteries are currently rated for due to increased degradation with abuse. Mini cycles allows more of those cycles without degradation but you'll still have capacity when you need it to last a long day without charging.

Wow thanks for all the information. What does bump charge mean exactly? Now my battery won't charge passed 90% either. A different one is on the way.

Try this, if you are rooted and have recovery wipe dalvik cache and cache. Power off phone and pull battery for like 5-10min. Hold the power button (with battery out) for like 1-2min. After letting battery sit out for 5-10min reboot and see what happens. If same instances occur. Your battery is dead just purchase a new one! Anker recommended!

You're welcome.
Bump charging is partially charging before battery gets low. An example would be running the battery down 25% and charging without overcharging it.

Had the same issue, bought a new Anker and issues resolved, the stock Samsung sucks!
I'm just glad there's a way to replace it that'll mean this phone can last a long time if I'm careful with it.
Yeah it must be these batteries. My mom has the Note 4 as well and hers does the same thing. As does mine

Yes the stock Samsung batteries are horrible. They don't last very long then they start misrepresenting the battery statistics to the OS so you get the shutdowns at 20 or so %. I switched to a twenty$ Anker I found on Amazon over 6 months ago and never had the issue occur again. Even thy sprint techs will tell you if you ask them outright!
