Anyone who says they are getting 24-36 hours on a regular EVO battery are either running with everything turned off and only using it to take phone calls, or they are lying.

The extended battery would last two days with light usage, maybe three if you just used it to make calls.

Face it, the EVO was designed to do a lot of stuff, and expecting more than a 18 hours of use from one battery charge is being un-realistic.

I have had mine 3500 since they came out. My phone, even with heavy use, lasts 12-18 hours with pretty heavy use, and still have 25% left. I have never tried to NOT use my phone to see how long it would last, nor have I turned off "unneeded essentials". I bought this phone to use everything, and thats just what I do.

As for everyone and their issues with charging. It is a HTC design to protect the user and the phone. Lithium Ion Batteries are a fire hazard if overcharged, so by trying to be at 100% is just pushing it. If you REALLY REALLY need to be above 90%, then do this. Let your phone charge its regular 8 hours (while you sleep), then when you wake up, unplug it and reboot it, then plug it back in. It will charge the last remaining 5-10%. You don't really have to reboot it, you can just let it go back to sleep. When it wakes up, it will show the real charge. Usually unless your trying to "Power Speed Charge" it, you should usually be about 90%, although I have seen it as low as 85%.

Another suggestion is to try a slower charger (one that charges with 500-750mA. It will charge slower, but it will be a steady charge, which will be more accurate. A lot of the issues are from people trying to charge at max A/h in the shortest time possible which contributes to more heat which makes the phone reading less accurate.

I hope this helps.

I bought my EVO the day it came out. It just died. How do you charge it? Is there some way to recharge the battery?
[EVO 4G Accessories] tonyb1900:
Thanks guys yea I have everything on except for 4g and I pretty much last 8 to 9 hrs with no idle time from the phone i guess investing in an external charger isn't a bad idea thought the super battery would last longer than that and I tried all the tricks to charging from the phone and that's the most I've gotten
[EVO 4G Accessories] Brutal-Force:
Currently Vaelpack, but I have also used Fresh/CM 6. Not really a big difference.

I had a tab break on my battery door and i contacted seidio but they said i need a proof of a sales receipt but i purchased it on ebay. is there any way i can get a replacement for my battery door?
[EVO 4G Accessories] Brutal-Force:
show them your Ebay Reciept.
[EVO 4G Accessories] Novarider:
if you bought it new on ebay they should honor the warranty. Just copy the page and send it to them

i bought this the day i got my evo, scared into because of horible exp with the palm pre. i get 2 days out of it :)
[EVO 4G Accessories] macmill:
This thing is a BEAST!

If you are hesitating to buy it... Just buy it - of course if you have the money!

The look of it seems much better than in pictures, I never look at the back nor do I face my Evo down so I do not even care but it doesn't look too bad. Feels good in my hand and do not really see a weight difference(just could be really excited though...)

It feels good not having to worry about my battery life... wanted to drain it to 0% took about 8-9 hours- Using: Pandora, Papastacker, Facebook, Rockplayer(1.36hr movie, starting at 30% then died at the end of the movie) 4g, GPS, HI-BRIGHT, and whatever else you can think of. No turning back, ever...:D

best news is that i just got home and my Seidio Extended battery got delivered today.. charging now.. might get 3 or 4 days off a charge after i cycle the battery a few times..
[EVO 4G Accessories] texasboylaw:
all i can say is if you dont have this battery you need to get it. i though people were exaggerating. this battery is a must have. i couldn't drain it at all. its not big at all it makes it easier to grip the phone now.
[EVO 4G Accessories] SouthernEvo:
I have to agree after reading the "OMG YOUR PHONE WILL BE A BRICK !" and getting the actual battery and opening the package I said out loud "Thats it ?" the back is not that big people . Plus the added phone life you get you will soo forget about the buldge in the back lol
[EVO 4G Accessories] hammysink:
mine comes today. thanks to this community i got it at a great deal.
[EVO 4G Accessories] robpet2:
Smh. Battery had 60 percent charge when I got it so the battery life isn't gonna be the best on this first charge. Gotta get it down to zero today. At 87 percent after 2hrs off charger

I've got two seidio 3500's, the seidio external wall charger, and the seidio innocase extended. I cycle my batts every twodays. Use one for 2 days while the other charges/sits. 6 hours before cycling I top off the second battery before replacing. I literally get two days with moderate use and I can't go back to stock. With the seidio it feels like this is the way the phone was meant to be. Easy to hold and long battery life. Congrats to the recent seidio owners. Now look into the innocase extended for a bit more protection. I can link to my thread if anyone wants to see it.
[EVO 4G Accessories] bobyboby:
not a good way to use the battery
[EVO 4G Accessories] lovethyEVO:
Better than letting it fall below the minimum voltage level for lithiums. On top of that, the evo can't charge these batteries for ****. Besides, two days on a single charge with moderate use....how do you expect me to use it? It's my money and I'm not shoving this battery down your throat so what I do with my money is really no cause for your concern.
[EVO 4G Accessories] bobyboby:
you don't have to get violent for this. you have your theory and money, just chill, ok? just a piece of dumb battery
[EVO 4G Accessories] bobyboby:
To anyone looking for extended batteries for the EVO, the ebay $10 3000/3500mAh have more bang for your bucks. I personally have Seidio 3500, Yoobao 3000, and ebay 3000 and 3500, and have done discharging test with a constant resistive load and data logger. The Yoobao one is good for the money too.

At this point, the Seidio is not quite worth the >$60 price tag; but I haven't done accelerated stress testing and compare the expected life span etc, also the customer service for Seidio is a lot better.
[EVO 4G Accessories] lovethyEVO:
You're right, it's a piece of battery. Honestly it sounded like you were coming off as being a smart ass and to be fair I can let it go.

You're points here are noted and appreciated. The customer service is the reason I went with seidio and not the ebay ones. Also, I purchased my batts from amazon so I have two places to fall on if I have issues with these batts.

As for charging, do you charge the seidios with the evo or an external charger? I found charging in the evo doesn't give it as full a charge as the external wall charger.
[EVO 4G Accessories] robpet2:
This is without discharging battery. I'm working on discharging it now. But it won't die

well i'll add to the list of satisfied customers.

i ordered my Seidio 3500 wednesday and received it friday morning. charged for 6 hours (in-phone with stock charger cable). then used it for 21.5 hours, including about 6 full hours of video games + wifi downloading and general use of the phone, before the battery got to 10%...

this is an incredible improvement for me as my battery wouldn't last me half a day. now i can leave my house and be confident that my battery wont run out on me before i get home:D

EDIT: alread convinced a friend to buy an Evo, he got it today...and convinced him to buy a Seidio!
[EVO 4G Accessories] ezkialrage:
my seido 3500 is actually getting worse. the last two days, after a night of charging on the wall charger, the batter barely lasts a day. maybe i have to reset my battery stats again....wish i didnt have to do that.
[EVO 4G Accessories] BrianDigital:
It's the way HTC made this phone charge, you will need a separate wall charger just for the battery to get a full charge
[EVO 4G Accessories] robpet2:
I was thinking about getting the separate wall charger from seidio but its almost 30 bucks for it. Just ordered the holster cause the one I have has a magnet that kills the battery at the same time its holding the phone.

Sent from my HTC Evo 4G
[EVO 4G Accessories] ezkialrage:
I do have a wall charger, the one that came from seido. i did say i charged it in the wall charger. i did this for a few nights to try and condition the batter for maximum charge, and then reset the battery statistics after the last one at 100%.

i just removed the yahoo messenger and the voice and video plugin, i think thats what was killing it even tho astro and spare parts didnt say it was running, that was the only thing i changed.
[EVO 4G Accessories] sanjsrik:
Sorry, not a true statement. I charge from my USB port on my computer and it fully charges to 100% every time.
[EVO 4G Accessories] Max_Pain:
I charge my seidio directly in the phone too, using the wall charger. I also get 100% but the first 5-10% drop pretty quickly.

Swyped from my HTC Evo 4G on the MetroPCS 1X network!
[EVO 4G Accessories] Novarider:
The charging bug is a well known bug. If you charger this battery in an external charger you won't get the fast drop from 100%-90% instead it will stay at 100% for a while.
[EVO 4G Accessories] Max_Pain:
Yeah I know of the bug...however I'd rather lose 10% of a ridiculously long battery life than have to take apart the seidio case and remove the battery everytime I want to charge the phone.

Do you think this charging bug can be addressed with software patch or similar?

[EVO 4G Accessories] robpet2:
best way to get full charge is to let the phone charge for about 1-2 hrs with the power off ( after the light turns green )
[EVO 4G Accessories] drtic:
My experience.

Charging from empty.

After 1:41h evo said battery is full. With 3,976V. But charging still continued. After 2:40 charging finished with battery on 4,121V. And startid cycle. And after 8h is battery on 4,199V. Should be full if full battery is 4,2V how somebody said. Only time for full charging is short..only 2,75h x 800 mA is 2200mAh. But battery shows 4,199V and should be full..so...i dont know conclusion :-)
[EVO 4G Accessories] ducvader:
With the extra bulk from the battery cover.... I was wondering if anyone had some links they can put up for some leather cases, or cases that will fit the extra thickness of this phone. I'm having problems finding a case since most sellers are selling cases fitting the stock Evo 4g. Thanks in advance
[EVO 4G Accessories] Brutal-Force:
I use the stock Tmobile G1 case and it fits fine. It was designed with snaps instead of magnets.

I would imagine that any G1 case would work.

I don't even have this battery yet and will tell everyone who is afraid of making their phone thicker.. TRUST ME, is not bad at all.. Not only will you get used to it, but you will eventually never understand how you did WITHOUT IT..

Plus, don't get all nervous about how ugly it looks.. When you go out at night, or wanna show it off, just put the stock one and back, BACK ON..

I will use mine daily for business, HOW IT SHOULD BE, not this, gotta plug it in all the time BS..

Then when its time to chill with the *****es :) its back to the sleek looking phone we all love...

Only IMO it still looks better with the thicker back then with a wire hanging from the bottom of it all the time..
[EVO 4G Accessories] sanjsrik:
So, let's see if this post is accurate and I'm understanding it correctly:

1. You don't have the battery yet, but you're used to it and they shouldn't be afraid of the phone being thicker, they'll "get used to it"?

2. You don't have this battery yet, and you're offering advice about it as though you do?

3. You don't have this battery yet, but when you use it for business (I assume for when you're not hanging out "with the *****es"), that you'll be looking really cool and never having to charge it.

3. You don't have this battery yet, and apparently when you "chill with the *****es" you take out the battery you don't have yet, tell everyone they shouldn't be afraid of the thickness (of the said battery you don't have yet), and it's better than the wire hanging out of the bottom?

Exactly how would you know all this when your first sentence is, "I don't even have this battery yet."?
[EVO 4G Accessories] fastfed:
Because I am GOD MOFO!!

I have a few friends that have this phone and battery..

A. Yes I have friends

B. Yes more people have this phone AND Battery(3500) than just people on this forum

C. I have had many smart phones and almost all of them have the Seidio ext. battery, there was a thread just like this one, in almost every other smart phone forum, including my old Touch, which is when I had an extended battery and others.

D.DOES IT REALLY MATTER?? WHAT I THINK?

E. I can tell you to buy a new Mustang even though I don't own one.. I could even give you some information on quality of build.. EVEN THOUGH I DON'T OWN ONE.

Why does this surprise you? I don't even understand why youre being a smart ass for no reason AT ALL. I was simply stating my opinion based on the things I listed!

[EVO 4G Accessories] blackroseMD1:
I got the battery on Tuesday, charged it for 8 hours in an external charger, put it in my phone, and it dropped faster than the stock battery. Last night, I put it in the external charger at 11:30pm, took it off at noon today. Right now it's 12:37 and I'm already at 88%.

I'm wondering if it's got a bad cell and I should send it back to Amazon, or give it another 3 days and see if it fixes itself through charging cycles. Honestly, right now, I'm only getting about 4 hours of heavy use out of it.

What do you guys think?

Yep, wiped battery stats when I put it in this morning after charging for 12 1/2 hours. The weird thing is, using JuicePlotter, it says that my battery is at 93% right now, however, my battery percentage in the taskbar, and JPs graph, show it at 79%, so I'm wondering which one to believe.

Well, I ended up getting about eight hours of light to moderate use out of it before I got down to 9% and threw it on the wall charger.

It's been on the charger now for 13 hours, and this will be my third full charge from single digits, so we'll see how it does today.

Mine starting holding a better charge after being cycled 3-4 times. I always charge on an external charger and get 40 hrs moderate use. I do notice that the first 15% drops a bit fast but I just ignore that becuz the last 20 % seems to last a very long time. I tried wiping batt stats also but it still show up the same.
[EVO 4G Accessories] blackroseMD1:
Well, it dropped down to 79 pretty quickly this time, but I'm going to run it down to single digits again and let it charge 12 hours and see what happens. If it's not better after another 2 or 3 full charges, then I'm going to have it replaced.
[EVO 4G Accessories] drtic:
When u finish charging check voltage. Full charged battery should have 4,2V.

htc evo 4G
[EVO 4G Accessories] lovethyEVO:
Wrong. The only time you will see 4.2 is when it is on the charger and even that is not a guarantee that it is fully charged.

I have personally seen my evo get to 4.2v and 100% battery but as soon as you unplug it it will display the actual voltage it is really at. 4.15v off charger is a better indicator of 100%.

With the extendeds, if you charge to 100% in the evo, take it off the charger and the voltage level reads anywhere below 4v you are well below 90% battery capacity. A reboot will show this as well. Charge the extended to 100% in the evo, unplug, shut down, wait about 5 to 10 seconds and then reboot. When the evo fully boots you will see that actual battery level.

You have to understand that the voltage you see while charging is more than the actual voltage of the battery.

This means that while plugged in you can see for example a voltage level of 4.128 and as soon as you unplug it it will drop to 4.054 (these are just random numbers but this is what I have seen personally).

If I can find my battery voltage readouts I will post them to give you an idea. But the point is that the voltage level is a good indicator of your battery level, just not the voltage while it is being charged.
[EVO 4G Accessories] drtic:
OK, i agree. I noticed when i unplug evo from charger, im from 4.2V to 4.15 in a few seconds.

I only had to say u can unplug evo from charger when u see 4,2V, because u cant trust how many percent evo shows u or if green led lights.

With seido 3500 evo signalize 100% and green light after about 1h 40min. Voltage is about 3.9V and when u unplug in that moment u are back to 70% in a few minutes of using. (in my case with stock kernel).

I only wonder when i unplug evo when battery shows me 4.2..(or real 4.1 when i unplug) if im full charged or just about 90% or so.

In other case im fully satisfied with this battery...after 12h im on 63% of moderate using. With setcpu and juice defender on.
[EVO 4G Accessories] blackroseMD1:
OK, so I just pulled the battery out of the wall charger, put it in my phone, and checked the voltage. It says "Status: 100/100 Voltage 4.104". Guess we'll see how it does today. So far, I'm still leaning towards having gotten a defective battery, but taking a wait and see approach for now.

Edit: Half an hour later and I'm down to 92%...
[EVO 4G Accessories] fast2049:
With my battery when I pull it off of the external charger it sits around 4.15 volts never gets to 4.2. Probably a safety feature. Did you try a different external charger?
[EVO 4G Accessories] blackroseMD1:
No, don't have another external charger available at the moment. I think I'm just going to have Amazon replace it, as I'm only getting about 3 hours of screen on time before it runs out, which is worse than I get with the stock battery.
