Hi fellow l9'ers
I purchased an OEM battery to have as a spare battery since I'm usually out of battery when I most need it but forget to bring it or charge it. After having so-so experiences with aftermarket extended batteries on other phones I decided that if I wanted good results on the cheap I need to make it myself. Still testing it out but initial impressions are good.
BTW.. yes it looks horrendous and I do know that it could blow up, ruin my phone, cause cancer and start WW3.... but thanks for your concern.

9/4/13 Update.... after using it on a daily basis and swiping back and forth between the oem battery and my jerry-rigged battery I can say its definitely working. The performance has gotten constant and I did a battery drain comparison between the 2 using the app called FAST DISCHARGE. All option selected and cpu set to full load with temp set to unlimited. I did remove two of the jumpers and only left positive and negative connected.
OEM BATTERY........... 2hr 5min 13 sec
JERRY-RIGGED BATT..........3hr 35min 21sec
I suspect that it doesn't last double since both circuits are being powered when charged...... the first battery to be fully charged send a signal to the charger to shut off hence the lack of full power.
Over all for $10 bucks I'm not complaining.
How does the battery stay in place? double side tape?
Also, what is the battery life on this uhmmmm... phone?
How is it?
I am very interested in trying this if your results are good...How has your battery life been affected? Has it doubled? Do you use a case that works with the new "power bulge"?
I did that to my old i897 captivate. you only need the positive and negative connected. you're connecting the two circuit boards together which may cause problems. i would remove that one. Unless you can find a battery charger that supplies more amperage you most likely will never get that battery fully charged no matter what the android meter says.
Ok, after a few days of heavy usage I have come across sporadic performance results. In a few occasions it would out last the original battery under the same usage and other times it would perform as a stock battery. I plan on purchasing an external charger since I suspect that both batteries are not fully being charged as the previous post mentions. I will also disassemble the second battery and take the circuit out of the equation. So far I am pleased with it's performance even though it's not consistent.

Cool. i work in batteries so i didnt check out dudes guide other than his soldering was good lol. essentially all you're doing is connecting the batteries in parallel. since both batteries have a circuit board that controls low voltage and temperature safety, you only need to use one as the battery will still be a 3.6v cell just double the capacity. stock LG charger shipped w/ L9 outputs .85 amps so if you could find one that did 1.5amps or 1500mah you'd be in good shape.
Like @Meda808 said,you only need to connect two pins... + and -.You will also need stronger charger but... There is a circuit in a phone which controls power to battery(I think that that's why is one of the two middle contacts on battery) so... Maybe with external charger?

Small update......
So far so good, no major issues. I purchased the anker standalone charger and it charges the battery but it takes way to long(10-15hrs) So I just charge it in the phone now. The battery lasts me a full day under heavy heavy usage. Prior to this by 2-3pm it was out of juice.
I have noticed that it has become less sporadic the more I use it.
Iheartradio 4-6hrs a day, dish anywhere 2-3hrs a day, calls:30-1hr. This is with WiF(thanks Home Depot), data and Bluetooth(LG Tone)on for most of the day.../.. I'm happy I did it.
I unplug at 4:45am and plug it in by 8-9pm with about 20-30% left.
I have not modified the connection yet so I suspect that it still might not be fully charged even with the aftermarket charger.
About the hump..... I got use to it quiker than I thought.
hahaha ill give ya props for ingenuity

Did HTC change the way devices operate when plugged in?
With the original evo 4g, it would run off the battery even when plugged in. Is that still the case with their newer devices (including the lte)?

I don't know the answer, but a fascinating question. Laptops don't run off the battery when charging (at least I don't think any ones I've ever owned do). So why should phones? They're basically little computers now anyway. I suppose we'll need a manual to know the answer, or an HTC rep.
While I agree with your assertion above, that was not the case with the original evo.
As is recall, this is demonstrated by using battery monitor widget or similar, with history enabled. The data would indicate that once the phone reached 100% charge, it would begin to discharge until about 90%. At this point it would start charging up again (until 100%) and the cycle would repeat.
If the phone is running off the charger while plugged in, the battery level should remain at 100% the entire time. Sure there were kernels available that would change the charge rate or thresholds. Anyone with an evo 3d care to chime in?

That seems rather silly - what if you grab the phone off the charger when it is just down to that 90% marker? It will show up as 100% I presume, and then drop rapidly down to 90%? Hmmm... No wonder those SBC kernels are so useful!
It's the same reason most new laptops give you a battery health option that only charges to 80% if you keep a battery at full charge for an extended period of time the cells will overheat and eventually lose some of their charging ability kinda like when you use a float charge on a lawnmower battery it's on a constant charge and discharge to keep the battery healthy same rule applies here.
Whatever they do/did, I hope it's well thought out, considering the battery is not removable. Once the cells degrade,...phone is shot. A bit disappointing. I'm not here trying to fight about nonremovable battery and how long it will last, and ability yo swap out batteries. But the idea that battery degradation (which is inevitable) = shot phone DOES give me pause and concern.

Even after a year, there is noticeable diminished battery capacity. I've had the seidio 3500 in my original evo since about feb or march of last year. Fast forward to same time this year. I'd say it easily lost 20-25% capacity. With my typical usage, I could go for up to 4 days without having to recharge (yes, light user). Now, it's 2-2.5 days. I was bothered by it enough that I did an rma. Seidio said that's normal wear and tear. Fortunately, the credit card I used had an extended warranty feature too, so that's what covered it.
There will likely be a tear apart video/howto posted eventually on the evo lte. Although the battery may not be typical user replaceable, i'm confident it is possible to open the device with minimal damage.
I'm sure there will be a way to switch batteried, you'll just have to go to a phone tech probably. I'm not worried anyways, I'm still using my stock evo battery and it's still going strong

I'm sure you can fork over some cash and get the battery replaced. I wouldn't lose any sleep over this. iPhones have survived with non-removable batteries for many years (although I always used that as a "con" in my comparisons between Apple and Google's respective phones).
My Evo 3D will discharge to 95% then back to 100% and repeat. It is done to keep the battery in good health longer.

This is true, But iPhone users have no choice. So they get used to it.
Android, at least for now, has choices regarding removeable batteries.
IPhone users also have a 3 1/2"? size screen, which they got used to.
I'd Never purchase an Android device with that size screen, even if it was available. I highly doubt they'd sell many of them with that size screen.
Reminds me of when I thought my HTC Touch Diamond's screen was so large, compared to my previous clamshell devices prior to that lol!
It was such a nice screen for its time, just like the iPhone was a nice screen for its time, but that time has long passed, except for iPhone users :-(

Im on my 4th day of using the 1900 one. it seems regular to me. ive been fully charging and draining it for a few days now. havent seen a great improvement. oh and props on the supser sayain rom playa. I got like 2 days of battery life with that. are you going to make the newer versions for the 351.3 leak? or does it not really matter.
Damn that sucks. Right now I'm just using the external battery pack when I can't plug in my phone.
Sent from my HTC_Amaze_4G using xda premium
Yeah same here. Not really a huge noticable difference. Then again a change in only about 200mah is not that much anyways. 1700 vs 1900mah
I have an Anker 1900 also. The life of the battery depends on how its conditioned. I also charge it in the phone and not with an external charger and I have noticed the battery life last longer.
I let the battery drain till the phone shuts off then charge it to 100%. I do that with my stock one as well. After a couple of days of doing that I reset my batt stats in recovery (4EXT of course) and continue the process over again.

It's Better To Fail At Originality

i have an anker and chichitec. both are better than the oem one. given that the oem one crapped out, i'm not sure how accurate my observations are, though.
One of the first things I did was get an Anker battery and honestly I couldn't tell that much of a difference. Granted I only had the OEM battery for about a week, but it seems like it drains at about the same rate, it might last just the tiniest bit longer, but its not much of a difference.

My OEM is slightly better than either of my two Anker 1900 batteries.
I have not noticed any difference really. I have to charge me batt. every night after a days use. I keep an original batt charged and another anker. I switch them out. no ground breaking changes.
Hello everyone,
Just ran across this site. It looks very good and explains a lot about charging and overcharging Lithium-ion batteries. Hope you find it useful.

the difference between stock amaze batt and anker (i doubt it's full 1900mAh anyway) is about 170mAh. def. not groundbreaking lol
After conditioning my Anker batteries (0-100 charge/discharge 5 times as recommended) using the external charger. I found that on average my batteries lasted about 30% longer than stock. Also I was getting random reboots, the grey battery icon error, incorrect battery % reports with the stock battery. All of that has stopped when using the Anker battery. I have also found that charging with the external charger will allow the Anker to last longer than charging in the phone. The Anker battery seems to operate at a lower temperature also. Overall I have definitely seen a substantial increase in battery life over stock. Although obviously not ground breaking it is a worth while investment especially with it being relatively inexpensive.

I also conditioned mine, and they don't last as well as OEM, certainly not 30% better. Maybe your OEM was defective.

If you want to compare properly – you need to calibrate each battery and use it with its own calibration profile. The results will be quite approximate otherwise.
I asked about app to switch battery profiles – nobody answered yet…
Even if it exists, it’ll work for rooted phones only, most likely…

I should think that a battery would work so long as it was stronger than the profile being used (the % might not be accurate, but it would at least run), but you bring up a good point.

So as we all know the more times you recharge a battery they eventually stop being able to hold a full charge. So what happens when say in 1 year the Evo 4g LTE can only hold 70% of a charge? Do you have to send it to HTC to get the battery replaced?
I could see this being a problem on thicker phones where the battery can be deeper in, but on this phone...
http://www.youtube.com/watch?v=LiKpHr8RLBs
The battery is a few screws away I'd be surprised if we don't see a few aftermarket batteries.
It will take way longer than a year to reduce capacity to %70 percent... for example my mac battery that is also lithium ion is 3 years old with 651 load cycles can hold %88 percent of the original capacity.
It will be fine past the two year mark I'd think. My Epic 4G's battery still still as good as new, and my Evo's battery wont be getting charged as much (because it lasts soo much longer).
What is the best way to condition the battery?
I'll just take it to Sprint and have them replace the battery. I have TEP.
I suspect you can take it to Sprint. I haven't had any issues with the battery on any my previous HTC phones. I think you'll have issues with the phone before you have issues with the battery.

Do less full charges. These are lithium batteries and they will last longer if you charge from say, 30%-50% to 100 rather then totally dead to fully charged. All the tutorials you see posted where it says fully charge, then deplete, then charge and deplete, etc don't work. Old alkaline batts used to have a memory and if you didn't do that they would eventually not charge completely. You don't have that issue nowadays.
I agree Bring battery down to a low percentage and recharge it fully.

I asked about batteries at Sprint store (repair store) 2 days ago. They said they are not taking apart the phone. They are going to replace the phone for battery issues.
I had a seidio 3500mah battery in the old evo. After about a year of use, it's capacity dropped to about 70%. The phone went from being recharged every 2 days (with a good 55-60%+ remaining) to about 20-30% remaining after 2 days.
Unless technology has improved in the current batteries, I believe we'll see similar results.

It's quite easy to take this phone apart to replace the battery. Just requires a Torx t5 bit and a small jeweler's philips. Really takes less than 5 min to disassemble and swap out the battery.

HTC EVO 4G LTE "Battery"
The battery is a 2,000mAh lithium ion battery degrades if you use it or not, so use it and which has an average of 500 charges, but rarley mentions if it's protected! In previous posts I seen various time of life pertaining to the battery and I just want to say that it all depends if your a power user or not! If the battery is not protected the battery will not be stable and can explode and or recharge up to 1200 cycles and puts out the correct voltage 3.7v protected or not and a LiFePO4 can charge up to 2000 time, but only puts out 3.2 V so I have to say this is strange knowing these devices needs the extra voltage! The only way to go is a Lithium polymer battery which puts out the correct voltage and on average can charge around a 1000 cycles and seems to have less drain on the battery compared to others! Protected batteries conversate back and fourth with the charger to maintain stability, but also counts the amount of cycles which is around 500 cycles for "safety reasons" Everything is marketing! I've been screaming about this video posted above and on the HTC Forum and they've been rejecting the reply's because they obviously want to hide this information! People spend more than this on a mp3 player than what they offer for a trade in and this is the perfect mini tablet/phone! I hope third party companies make batteries for this phone! (((A little off course, but helpful is when your old power tools battery dies "nickel cadmium" you can shock it with twice the voltage by scraping the connection with the appropriate voltage and will burn the crystals off that stops it from charging because this battery has a memory!))) HTC put out a update recently that caused a issue with battery lose for the HTC EVO 4G LTE and it's all over the forum there! funny how this all goes hand in hand! Sorry for the long message, but sometimes helpful...

okay so i just received my 3240 ext. battery...i will do several tests once fully depleted and properly recharged...the battery was slightly below full charge upon installing...Im trying to make these tests as scientifically accurate as possible (variable free and unbiased). once i get this first cycle done.
i will test according to the following:
*i will not test with any variables (this includes signal strength), so while running these the phone will be in airplane mode
*also to ensure consistency i will wipe the phone completely and freeze any apps that arent critical to the function of the phone
(although im tempted to install neo adrenaline 2.0 for these tests, if only to eliminate any bloatware from skewing results)
*aside from unlocking and superuser (needed to calibrate the battery after first full charge), unless otherwise stated, the phone will be completely stock (605.12)
(unless i do install adrenaline 2.0) either way the tests will be coducted in the same manner each time including rom and apps installed
*in accordance with the least amount of variables rule i will keep the phone at full brightness, screen on, while running a stress testing app (this will help shorten times between tests as im trying to kill the battery as quickly as possible
*these series of tests will take quite a while to do
(hopefully, if all goes well and if this battery is up to its snuff, itll be a ***** to drain)
*results will be published at the bottom of each full discharge cycle (phone turns its self off), and will continue to post results until the 10th discharge
*on the 11th recharge i will enable the antennae and rerun the test to see how much the signal strenght and such affected the actual life of the battery
Any suggestions on what else to test for or if im missing anything?!?!
i know setcpu has a stress test built in but id like something to stress test the gpu and cpu at the same time if at all possible, any suggestions are welcome.
which apps would you like to see used in the test, since i know setcpu isnt the best option for this...ive heard battery monitor widget stated a few times in other threads since temperature is also a key factor, i will consider it.
comments, concerns?!?!
if this turns out well i will run these tests on other batteries...
theres no way im going to pay for a mugen power battery...so i propose a wager...ill gladly pay for one if it does out perform every other battery i get my hands on AND if the power rating is with in an acceptable range of their official rating (4000mah) upon completion of testing...
ill contact mugen power and set up the challenge
There's an app called Stability Test in the Play Store that has a CPU/GPU stress test mode, and it supports multi-threading, so it should work for what you're wanting to do.
awesome...i will look into it
how did the testing go?
I just got my laza cell 3240mah battery myself, only gone through 2 cycles so far. I've also got the following batteries if you'd be interested in testing any of them.

this battery is great.
i have had some problems with the phone rebooting, but that could be my phone, not the battery, and it doesn't do it all the time.

Laza extended battery
I bought an extended Laza battery on Amazon an I've been using it for a couple of days now. I'm only on my 3rd charge cycle but I can see a major improvement in battery life. For $30 (including shipping), it seemed to be a good deal.
What I don't like about it is the back cover that comes with the package. The antenna material inside the cover is pasted with some really gooey adhesive and it's a lot thicker than the OEM stuff. That makes the closing of the cover difficult, as you have to squeeze the antenna between the phone and the cover itself. Also, I noticed that one of the tabs for holding the cover attached to the phone was missing on the volume rocker side. That causes creaking and leaves a gap between the phone and the cover on that side. There is also a gap at the top, that never closes, as the retaining tabs are in the wrong position. I wrote to Laza and they said they'll ship a new (and tested) cover to me next week. I'll report more when it arrives.
Is the battery percentage accurate with extended batteries?
Sent from my ViperRezound via Tapatalk
I received the second cover from Laza and it seems to fit just as poorly as the first one. Also, it was supposed to be tested for the 4g reception, but it drops my 4g twice as often as the initial one. The battery is holding its ground and charges to 3248 mA overnight. With 4g enabled and moderate to heavy use of the phone, it lasts 6-7 hours max, with juice saving tweaks and the screen at 30%. I haven't made up my mind if I want to return everything and get the OEM battery and cover, or just keep this stuff and deal with it's shortcomings. Obviously, I can't recommend it to anyone due to the poor quality of the back-cover.
Sent from my ADR6425LVW using xda app-developers app
If this battery lasts longer than the Verizon extended battery, I'd be interested in just the battery without the cover as I use the standard cover cut to allow the extended battery to stick out, and then a modified defender case.
I think he could sell the battery alone for half the price, but does not do so at this time.
I use this battery with the OEM extended back cover. After extensively running data speed tests(nothing official just a million runs using the speedtest app with each cover) I was able to determine that the LAZA battery does in fact run cooler, as the Amazon reviews state, than the OEM batteries. It also gets longer battery life than the OEM extended battery, however i have no numbers for this just regular usage/charging times i had. But between the 2 LAZA back covers, i never seemed to be able to snag quite the dl speed i got with the OEM covers, however my upload speed on the LAZA covers strangely doubled what the OEM covers got. Who cares about the upload speed though obviously dl is more useful! So in general LAZA battery with OEM extended cover gave me the best results for heat, battery run time, and data speed. Reception between all the covers(OEM extended, 2 LAZA extended, OEM regular cover) was virtually the same. I hope this info helps someone because i know when i was looking for this exact same comparison i could find nothing except for the shady Amazon reviews.

there is no drop in the 4g
i have had this battery for a couple of days and i can honestly say that my 4g reception has been better! Laza updated their product because they saw all of the complaints that's why it says "extended battery 4g" when you get it

Charge Regularly
To get the most out of your smartphone's battery, you'll need to charge it properly. Most smartphones have a lithium-ion battery that lives longer when charged regularly. Unlike the nickel batteries used in older phones, lithium-ion batteries do best when kept above a 50 percent charge. Repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity. If this happens, you'll need to charge the battery more frequently and it may last only a few hours before needing a charge, for example.
Your battery will also perform better if you don't let it charge to 100 percent, so take it off the charger at about 80 to 90 percent capacity. Leaving the phone connected to the charger when the phone is completely charged may lower battery life if you do it repeatedly.

Gees! Below 50% really. I would tend to agree somewhat. I never let my phone fall below 20% and usually charge until 97% more or less. But 90-50. I don't want to be walking around with a battery back. I need my phone to last all day and 40% of the battery just won't cut it.
Xuck that !! I have a 3000mah battery for a reason if it goes then it goes ill most likely have another phone by then.Not gonna sit here to nickel and dime my usage that's not why I got this phone .
GM makes the Li batteries last in the volt and bolt 10 years by not letting the car drain the batteries more than 2/3rds down, leaving the batteries at 1/3rd charge. Tesla does it too.

Nah, I don't own my phones for more than a year so this doesn't apply to me. I'd rather keep using it from 100-1 just like I've been doing for years. I wouldn't be able to stand only getting an hour of use and charging it 3 times a day.
This battery information applies to all devices that use this type of battery be they Samsung or other brands. Its not just the Note 8. It applies equally to your Oral-B tooth brush! :laugh:

this is a good habit to charge often at 50%. i usually let the battery run down to like 20% or less then charge. then when i have to go somewhere and i cant play with my phone anymore cus i worry i going to run down the battery.
Question are the "300-2500" charge cycles just as it says? I mean if I put it on the charger in the car for a 10 minute drive is that a cycle along with an overnight charge? If it is we should really only be putting it on the charger from the 50-90% with a guaranteed fast charge time of at least 30+mins to get the maximum charge cycles for the lifespan?

This was a really well written down to earth article about battery care. Thank you. I still have friends, family, and coworkers that insist on running their batteries to 0%. I can't convince them otherwise. Although my batteries degrade, it's never been anything easy shattering. Just notice an hour or two shaved of over a couple years life. As the article states, there is no way around this and I won't be a slave to my battery. In that note, I top off when I can.
My battery on my old phone tended to get to around the 40% at the end fo the work day, then I'd plug it in usually around the 20-30% and it still lasted 2+ years 'til I got a new battery. Now it's about 50% at the end of the day. But with Fast Charge, what do they expect people to do, plug it in for an hour, then unplug it, then go to sleep, wake up with 60% battery, go to work and then charge it for an hour when you get there?
The lie of requiring a non replaceable battery for water proofing is also an issue. Forced obsolescence sucks....

Too black and white.
It is possible to offer some water resistance to a mobile that has a removable battery, S5 for eg.
In general such water resistance is small and is often abused by the owner causing problems. Hardly any owner reads the instruction manual that outlines what ones device can and cannot do, what the IP rating means in REAL terms etc
"Forced obsolescence" mmmmm, a battery can be changed in the Note 8. I understand your point though.

this has been around for years. Doesn't make it very convenient to use nothing below 50%! I'd need at least an 8000 mh battery!! Therefore Samsung IS using too small a batteries in its top of the range device!

Totaly agree......
We then have to ask 'ourselves' WHY! Who forced Mobile brands to make anorexic devices? WE DID. We wanted thin small large wide slim ...........we got it and now pay the price.
I personally don't care if the device is thicker with a larger battery, for me its not a problem. For so many size was a major issue so the manufacture's listened and came up with these ultra thin mobiles that are vulnerable to dropping and breaking etc. off topic.
I find it totally bizarre that we spend mega bucks on such devices only to find we are educated to use them on software that reduces said mobile to the performance of a phone costing 100€! I may add many posters where disappointed when the Note 8 didn't have a 4k screen! Can you imagine the battery issues then?
Now we read this Samsung article and find we would need to charge our mobile several times a day as well as run it on a vastly reduced software programme. In reality that article is saying the battery is only operating efficiently at 40% of its total capacity before we start to degrade its life! Its all so absurd. What are we doing here folks?
Only one answer to this, either drop the performance OR vastly improve battery technology and fast.

I'm not sure how usefull this is for the new samsung phones though, as the release of the S8 Samsung improved the battery.
Samsung Mobile R&D VP Bookeun Oh told me, "I focused on maintaining the durability of the battery over the long term, over hundreds of charging cycles. For example, after approximately six months of normal usage, the battery in the S8 will outperform previous batteries. While most batteries hold about 80 percent of their charge after two years in usual cases, this battery should be capable of 95 percent of its original capacity."

PC mag S8 review
I am sorry but i will use my phone all day and charge overnight. If you can't use past 50% what is the point???? My pixel xl i have had since day 1 and use all day everyday and charge overnight and noticed no real decrease in battery life except a little change with oreo!
Outdated info and not necessary.
0% on your device is still considerably above what is considered the bottom line cell voltage before excessive discharge detrimental affects capacity.
A lot of engineering has gone into these devices to squeeze every possible mAh out of the packs, have a decent life expectancy AND operate safely. There is no need to strive for certain numbers and forcibly change your usage habits. There may or may not be a demonstrably better result long term but honestly is it worth worrying about?
And for removable packs...
Forget it. That's a thing of the past.
If devices had battery life like the Skyrocket, sure I see the NEED for a swappable pack.
But not now.
Having a sealed device makes it feel solid and keeps intrusion protection intact.
Holding an older device in hand, it seems almost laughable today. It creaks and groans and feels super cheap in comparison like some dollar store toy!
