3500mAh Seidio Battery - My Review (so far)

Hi all,
Just wanted to share my experience with people who may be considering an extended battery for their 6800. I recently decided to take the plunge on the super-extended battery after ditching my home phone and going cell only. Between the email checking, web surfing, texting and phone calling, the stock battery wasn't even lasting a day before crapping out. I attribute some of that to the fact that I have very weak signal in my office so often times while at work my data connection will drop and reconnect.
So early this past week my battery arrived. Install was cake as expected, though the battery door doesn't fit perfectly. It is just slightly raised in the middle.. hardly noticeable, but there. Seems like the hole for the white camera flash LED isn't quite big enough to fit around the element, too. I was initially worried about the extended backing being an annoyance, but after a week of heavy use, I've found the phone is MORE comfortable to hold, albeit slightly heavier (which I've never minded at all). With the battery on, it feels to be about the same weight as my old Treo 650 (god I HATED that phone LOL).
Ok so here are my typical settings :
Bluetooth : Off
Wifi : Off
GPS : Can't use it yet.. to chicken to install custom ROM
Email : 2 accounts, one set to check for mail every 15 mins, the other every 4 hours.
Backlight : 60%
Auto-Off : 2 minutes (screen and sleep mode)
Data Connection : 24/7
Software Running Full-Time : SPB Mobile Shell 2.1, SPB Diary today plugin, VITO SMS-Chat, Personalizer
I am a very heavy text and picture mail user and do a fair bit of web-surfing. Voice usage is light to moderate.
This past Thursday evening I decided to try to see how long it stretched from full charge to zero. I plugged the phone in to the wall charger and charged it up to 100% (around 6pm). With my normal usage pattern, and without plugging it into a PC to sync (so no short recharges), I was at 30% by 10pm on Saturday night. In an effort to kill it so I could recharge overnight, I used media player to loop a few full-screen WMV videos as well as turning on Bluetooth and WiFi. The bastard was resilient, though. At midnight, I still had 5% charge and "very low battery" warnings. To kill it the rest of the way, I surfed around the web for a bit.. it officially keeled over at 12:23am.
So my first official test of the super-extended battery netted me approximately 54.5 hours of "normal" usage with the afore listed settings which includes a couple hardcore hours of me making an effort to take it from 30% to zero. Having not intentionally killed it, I'm sure it would have lasted much longer.
In conclusion, I'm extremely pleased with the Seidio 3500mAh battery. It certainly delivers on it's promises. Thankfully I've never been bothered by a bulky or slightly heavy phone, so the extra weight isn't a factor for me. If anyone is on the fence about buying one, I would say go for it. If you're a heavy phone user you will really appreciate the extra juice
Oh yeah, one more thing, the extended battery does stick out enough to make the phone ALMOST too big for my leather bag/case thing. It was a universal leatherette belt-pouch with the magnetic click locks on it. The phone still fits but it's a super tight squeeze so I whipped out my much-loathed VZW rubberized holster for the time being. I have a Seidio spring loaded holster on order, hopefully it will be here tomorrow or Tuesday.

Just wondering if the spring loaded holster fit with the extended battery?

I think I read on the actual site that it does. I velieve I was reading the ext. battery product info. I have the Seido black rubberized case and the spring holster and was thinking of upgrading as well.
Hopefully, themirthfulswami will inform us soon.

I second that experience - best change I've made to my mogul.
Before using the battery, it was a race to see if the battery died before the end of the day. Now I can miss a night or even two of charging and it doesn't even matter.
A word of warning: The mogul is already decently large. Adding the extended battery pushes it to the edge of being useful in one handed operation. Not that it isn't, you just have to learn to hold it slightly differently.

Hello
I have tried few 3000mAh batteries and they perform great. i get to use my Titan for 4 days without charging... If anyone is interested I can get them for you for 35$ with back door included...

Who do I need to send the money to get the extended battery?

So I noticed the original person never got back to completing the review. So here's my two cents:
I'm generally a heavy phone user, especially with texts, emails and web surfing due to job reqs. Here's my typical settings:
WiFi- off
Bluetooth- off (on roughly 1 or 2 hrs max a day)
Brightness- 100%
Email: 2 accounts, 1 checking every 5 minutes (Yea, I actually need it) and the other receiving emails as they arrive (meaning I get them immediately upon receiving)
Auto off: 1 minute
Data Connection: On at all times
Software Running: Just switched to Manilla 2D- definitely a cool program to check out, SPB Pocket Plus (no today plugin)- using it to flick through IE
Texting: I don't know how many I text/day but I've hit 3000 in a month
Talk times: light to moderate
So I've never actually drained the extended battery to nothing, since I'm still used to charging it on a daily basis. I generally start my day off at 6 in the morning, its now 2:00 at night and the meter shows 50%. So typically speaking this thing beats the original battery by a lot. I won't charge tonight and see how well the battery does tomorrow. Along with the battery, I also got the extended battery case which fits snuggly and also covers that "middle lift up" the original person had a problem with (I guess its a problem with all the battery doors). I also have the spring holster- which fits both regular and extended battery phones.
As for how well the battery will stand up to my rigorous usage- I'll update you all once I'm through with tomorrow

big batteries need a fast charger
I put my 3600mAh Mugen in the charger at 10pm and remove it at 6am. If I try to it with the standard XV6800 charger (250mAh/hour), it won't charge all the way. Instead I use the 450mAh charger that I bought on eBay to charge the Mugen outside of the phone. Except I don't remove the battery from the phone; the 450mAh charger uses a standard USB cable, so I simply plug the cable directly into the phone.

As to that, I haven't had any problem charging the battery up to full using a regular charger. I generally plug it in probably 12 or 1 pm and unplug it at 6 or so. Then again, I never fully drain my battery.
As to the "review" that I had going yesterday, I am currently at 20% after 38 hours of use. I'm guessing this 20% will last several hours more since it was on 30% for several hours before

I just got one of these battery. When i plug into the charger the charging lite just blinks. Left it like this over night and still blinking.
Does this on 3 chargers:
1 - 5.5 V @ 1.0 A
2 - 5.4 V @ 2400 mA
3 - 5 V @ 850 mA
Any help ?

Are you using a seidio battery?

Yes the Seidio 3500mAh battery is the one that wont charge. My stock battery charges fine.

Hm..are you using the charger that came with your device? If that doesn't work..its most probably due to the battery. Seidio has a warranty on the batteries they sell
Email them first and ask what you should do, you most probably will have to ship it back if anything

Leaving the battery out of the phone for a minute or so when changing has seemed to fixed my problem of charging the 3500mAh Seidio battery.

Glad to hear it! Enjoy the crazy long lasting battery life we've never had before with the stock ones!

I actually bought this battery off of someone used for 3 months. Life is way better than my original battery. My original was real funny. If i'm doing nothing, it would last a few hours with extremely basic functions including screen off for majority of time. If I was to make a phone call, battery would die literally after 10-15 minutes of constant speakerphone talking, even from a full charge. Pissed me off, I use my phone for many things and sh*tty battery limited me heavily.
After installing this new battery, I am using my phone for everything again. Slingbox, navi, bluetooth music listening, web surfing and ofcourse phone calls.
I am able to keep my phone off of charge for up to 2 days with heavy use. I work out everyday or try to and I watch tv through slingbox on my phone with Jabra BT620 bluetooth head phones. Thats a lot of drainage. Yet phone still does well with 2 days of use and no charge needed. I have emails set to come in every 5 minutes as well.
Here is one major issue this battery has presented to my phone when I originally got it but doesnt happen all the time. The beauty of our phones is that they are real easy to open and close. Real smooth. But can close very fast. First few times I closed it, it slams so hard I guess that the battery gets knocked out of place. I have to remove the battery completely and put it back in to start my phone up again. Very annoying but tested a few times and it doesnt seem to happen all the time. It has happened to me maybe 3 times since I got battery (almost a week) but it happened maybe 2 times on the first day.
It depends on how hard you do it. As I was typing this, i tested it a few times. Opened and closed pretty hard like 4 times in a row with no issues. 5th time, I did it harder than I normally would and it happened again. Aside from this, very happy with battery.

hm, never had that problem you had. But in general- lets agree, the battery is a lifesaver for any powerhouse user

Ok, so the battery is great, but what about Seidio's customer service? Here's what happened when I ordered the battery, along with a charger, hard case, and a few other accessories...
"Dear [my name here],
Please refuse the package for the carrier. The order arrived to your address belongs to another customer. Please contact customer service at 832-204-1118 for any questions.
Once we received the package, we will reship your order ASAP.
Regards,
Seidio Customer Service"
I paid for 2 day FedEx delivery, yet they want me to refuse delivery, and then they won't even send the right stuff out until they get the wrong stuff back? My wife needs the battery for an upcoming business trip. She can barely use her phone today because the current battery doesn't even last a single day anymore. Besides, I didn't get this e-mail until yesterday on the way home from work, and the package was on my front porch when I got home.
Of course, customer service was closed for the night, so I replied asking that my correct items be shipped out in an expedited fashion and offered to return the incorrect package however they wanted me to. I'll follow up today with customer service once they open as well. Wish me luck!

Here's an update to my Seidio shipping issue. Apparently someone else with my same first name placed an order at the same time, and somehow ours got switched. When I called this morning, the person I spoke with said the same thing as the e-mail, that I would have to return the package and then they would ship the right one once they received the wrong one.
Since we really needed the extended battery, I went ahead and placed a second identical order and chose next day shipping. Then I called them back to cancel the original, but to my surprise the person who answered knew of my situation immediately and we came to the following agreement. I would return the package I received, and at that point they would refund my original purchase price plus the cost of the next day shipping, meaning I am still paying 2nd day shipping for something that will have taken over a week to arrive. But hey, at least I'll finally have it, and my wife will be able to use the extended battery on her business trip.

that's good news, seidio doesn't seem like they'll have bad customer service, its a great battery tho with the case it is somewhat of a brick haha..hope you enjoy the new extended life of it!

Battery life - how long?

Ok, so the Diamond has a poor battery life, but how poor? How many hours do you get out of yours without any ROM changes? How many hours do you get after tweaking and with ROM updates?
What about the newer extended life batteries? How much more life would they give? 20%? 50%? 100?
Thanks,
Jon

My battery lasts for about 4-5 days with normal phone and PPC usage.
(ROM 1.93 and no internet connection/3G/GPRS or GPS turned on).

Charge twice a day
I charge mine twice a day. I am a heavy user and have exchange server / push mail on all the time.
For this reason i have two batteries and change them every moning and afternoon.

If you rationalise it: Lets say with the 900maH you get 2 days, then what is your last question about. If you get the 1800maH battery then, then the life is dubbeld. Looks like a no brainer to me. Or do you expect us to guess at what your going to use, how long, what power it uses and then make a guess at the time?
Mine was tweaked and lasted more then a week, while on standby.
btw: Why not all your questions in 1 topic?

Twice a day!!! Is that all! lol
I have mine on the charger at night; then if i'm on the computer the diamond is plugged in via the usb port; my half hour commute means she's plugged in the cars cigarette lighter, and it's plugged in a charger a lot at work. I'm a GPS, 3G surfing, mp3 playing bandit though.
If i aint doing any of the above, and use it just as a phone the battery will last a while. (at least 2 days) But if i just didnt want a phone...

With normal battery you can only watch two movies on Coreplayer and you're out. With GPS on you get 2-3 hours max. It's almost scandalous.
If you only use it as a phone, you get decent battery life, but I've bought it to also use it as a PDA. The battery is simply insufficient.
I've had to buy an emergency charger which lets you charge the battery on the road using any normal AA battery.

My solution to the battery problem

No matter how you look at it, the battery life of Diamond is dismal. You can only last a day if you don't watch movies, if you don't listen to music, if you don't use GPS. But then, why did we buy this phone if we won't be able to use it?
I was fed up with it, so I bought an emergency charger like the one you can see here:
http://www.cdwg.com/shop/products/default.aspx?EDC=1113988
Now I can use normal AA batteries to charge my Diamond. A rechargeble battery of 2700 mAh can charge it 3 times which will last the day no matter how much you use it.
So if you carry around a few normal AA batteries with such a small charger like I do, you don't have a battery problem anymore...
UPDATE (actually a sad correction): http://forum.xda-developers.com/showpost.php?p=2502994&postcount=32

Very good idea. It is one more thing in our pocket, but it can be very usefull in some cases.

The American Diamond comes with a 1340 mAh battery... So it shouldn't be as troublesome as your 900 mAh power source.

and are they bigger ?
Could u give us the dimensions of your phone with this kind of battery ?

A 1340 mah battery would last only 50% longer than the standard one. A charger like mine with an AA battery would make the phone last 300% longer. You only have to carry one more thing in your bag.

With your cigarettes, your wallet, your keys, etc.
Yeah I know I should quit smoking then !

I wonder if this would work: http://www.dealextreme.com/details.dx/sku.8103
It's obviously not as efficient because it only uses 1 battery, but it's a lot smaller.

I used one of those at Glastonbury this year on my old nokia n73 all it does is give you an emergency charge say 2 bars on a nokia. Enough to make a few quick calls.

or something like this?
wonder if it will work on a Diamond?

According to some specs I have seen for the "HTC Victor" on the Sprint network, the thickness of the phone increases to 0.6 inches from 0.5 Inches (14mm from 11.5mm)
I for one would be happy to add an extra 2.5mm to my phone to get the increased battery life.
I believe its a bulkier battery with a deeper back cover.

All HTC devices have crap battery life, its generally because people use them for things other than phones. Im sure if you did all what is stated on a normal phone then it wouldnt last much longer than a day as well. I know my Sony Ericsson will probably only last 2 days if I just have a bluetooth headset connected, and thats without making any calls, watching videos or listening to music.
Top Tip, carry a travel USB cable with you, youre never to far from a PC... When Im away on business I keep my diamond and TyTn plugged into the lappy all the time.

Car charger
I use a car charger. It is more practical.

I have no battery problems at all with my Diamond. The battery was pretty bad at first (would only last a day), but now it's fine and I can get 3-4 days out of a single charge.

In-car charger plus desktop charger when at work. Result? Infinite battery life!

Im with the fella above,
Bought an extra mini-usb cable and carry all the time with me.
I have in the car some of those carchargers with usb out (of a non working FM-RAdio USB that bought for 4 euros), at home i use the DC charger at the office i connect it to the laptop.
All HTC have battery problems and diamong beeing a small unit, its a price to pay.
Same to the iphone in 3G mode.

to be honest since i bought the phone and charged it a couple of times, i get a 3 days tops usage with music, calls and all the other clicking. i don't know about you guys, but so far i'm quite happy with my batery life, and i haven't been using it for more than 3 weeks yet.
and in case i will eventualy have this issue, a spare batery will do the job

My bat life is also OK now. Any of you guys considered to buy a spare bat - it's the smallest soultion I think, but of couse you need rebooting the phone.

This is another good solution.... I think

YEEES ! that's the solution ! I'll stop using my Diamond for what i bought it for !
And maybe, buy instead a nokia 1600 !
But what you say is true... I have an old SE that is used only to wake me up... it lasts at least 1 month without charging !

Tilt Battery Drain During Phone Calls

OK, I know battery life is always an issue with PDA phones. I'm never far from a charger. I'm fine as long as I'm just checking e-mail (4 accounts, once an hour) and a little light web surfing with Opera Mini.
The problem arises when I use my phone as...well...a phone.
My Tilt loses battery power at an alarming rate when I'm talking on the phone. A 20 minute conversation will easily cost me 40% of my battery.
I'm usually in a non-3G area, so I'm on Edge. I normally have a good, strong 4-bar signal. Even when I'm in a 3G area, I use a different comm manager to turn off 3G to conserve power. I use KaiserTweak and select all the "Advised" settings in the power-related sections.
I've tried several different radios, but haven't noticed an improvement.
Does anyone have any ideas or recommendations on improving the efficiency of my Tilt in phone mode?

I have the same problem.
I have 3 batteries. 2 Samsungs and 1 Dynapak. Each battery lasts about 3 hours in standby. The phone is always warm as well. I have a utility that shows the phone is running around 380mAh current. That's seems pretty high.
I think theres something seriously wrong with certain batches of these phones.

these phones r seriously poor for battery life.. i love the htc but they slowly being overttaken by other phones.. shame!

maybe depends on the battery and ROM/radio because my Kaiser lasts 1 gay of VERY heavy usage+calling, and in stand by can lasts 6 days at least.

mine too or maybe more. Normally I charge every 2 days.
Seriously though, hasn't this topic been beat to death with a stylus?
Ask youself this, how is your battery and what all is running on the phone?
If the battery is a year old then just accept that it's shelf life is over with. If your phone is always warm that would general mean that one of the radios is running, Wifi , data, gps? If any of those are running all of the time or when you are not using it, then your draining the battery.
I have a friend that beat himself up trying to figure out why his battery would drain so fast, he reflashed the phone 3 times a day etc etc etc. He just could not accept that it was a crappy battery. I got another (used battery) and it worked fine.

"Am kinda joking but my stylus is now half the size due to this topic"

Buy a new battery.
I don't dig long phone calls unless there is something going on. Too many people just want to hang out on the phone and say nothing.

This isn't my first foray into these HTC devices. I've been using them for nearly 2 years now, and I know the battery life on these devices isn't what it is on something like my old RAZR. I'm just fine with that; since the Tilt does so much more, I don't expect the charge to last a week like my RAZR did. But this drain while using the phone is driving me nuts.
FYI, I know to keep WiFi and GPS off, and to use KaiserTweak to shut down data connections when they're not being used. If I don't use the phone or surf, the battery will easily last me 2 days, and that's with checking 4 e-mail accounts every hour, and with SBSH PocketWeather getting updates every 2 hours. But talk on the phone, and it's a different story. I talked to my wife for about 30 minutes last night and went from 80% to 20% battery level.
The battery is only about 7-8 months old. Still, I ordered a new 1600ma battery last week, and it should be here in a day or two. I'm hoping that solves the problem.

It's possible that the battery you have now is under warranty. (if you bought the phone new)
good luck.

Unfortunately, it was a refurb, and the warranty expired a long time ago. The new battery wasn't exactly a budget killer.

Well my battery seems to be working now.
Phone is no longer hot all the time, and my utility says I'm using between 1 and 64 mA. That's much better than the 350+ mA it was sucking before.
I didn't do a damn thing different either. Didn't change any settings for the radios, didn't reflash, etc..
Some people think that the GPS get's stuck in the "on" position and there's no way to turn it off, short of opening and closing GPS Aware programs repeatedly until your current usage drops in the sub 100 mA range.

Always discharge your battery fully as possible at least 1 a week to ensure your battery last longer, lots of charges above the threshold will diminish your batteries life and capacity. The Kaiser is a powerful device and it is obvious to anyone that this requires power to run it, so the battery wont last for days. :-(

HUH???????
These are Lithium batteries, we aren't in the 90's anymore buddy.. My phone lasts for at least 2 days and sometimes 3 (the phone is over a year old too)..
Welcome to the year 2009
"1. Battery Memory - When I first got my new cellphone, my friend recommended to fully drain the battery before recharging it. His reasoning was connected to the idea of battery memory. Allowing the battery to fully discharge then recharging to max, supposedly gives you the complete battery capacity. Otherwise, if you simply charged from the half way point to max battery capacity, the battery would treat the half way point as the empty point, thus cutting your battery capacity in half.
Problem is battery memory doesn’t apply to Lithium batteries, this advice was meant for Nickel based batteries. Fully discharging your Lithium battery frequently can actually be quite harmful to your battery’s health, possibly rendering it completely unusable if energy levels go too low.
The good news is today’s lithium batteries have a safety circuit in place to insure the battery doesn’t reach the point of no return. The safety circuit isn’t fool proof of course, if you leave your battery completely drained for a few days, even the circuit’s protective measures won’t save it.

INFACT it's recommended to leave a little bit of a charge before charging or storing.

Be that as it may, when you get a new battery you still have to use it for a few weeks before the phone reports battery levels accurately. The phone may still shut down when WM thinks it's almost empty, regardless if it's actually empty or not. Just try it, battery life improves over the first few weeks of usage, and your battery level readings will get more stable (instead of dropping to 50% in 10 minutes and then proceeding to stay there for 6 hours).
BTW my kaiser lasts about 3 days as well, with fairly heavy usage.

No fair, I want a bazillion stars next to my name too.
I Think this guy has had the phone and battery for a little while, so the few weeks thing might not be an option. (well at least the battery he was posting about)

HUH???????
These are Lithium batteries, we aren't in the 90's anymore buddy.. My phone lasts for at least 2 days and sometimes 3 (the phone is over a year old too)..
Welcome to the year 2009
"1. Battery Memory - When I first got my new cellphone, my friend recommended to fully drain the battery before recharging it. His reasoning was connected to the idea of battery memory. Allowing the battery to fully discharge then recharging to max, supposedly gives you the complete battery capacity. Otherwise, if you simply charged from the half way point to max battery capacity, the battery would treat the half way point as the empty point, thus cutting your battery capacity in half.

As refered to your reply, i didnt mean discharge fully completely i meant the cut off point would stop you anyhow, i meant to bring it to about 10%, i found that using the battery until it reaches 10-12% far by decreases battery drain when it is fully charged again, this is only 1 in a while though not frequently. I understand lithuim-ion doesnt have a memory effect problem, but there is such thing as variable current influencing different cells which can either benefit or make it worst, there is a lot of debate as to whether this improves it or not.
Great tip, keep it cool and away from your pocket pants because heat kills it.

Dude thats no fun to keep it out of your pocket,

How **** is this battery?

Very **** it would seem. I only used tomtom for about 15 or 20 minutes today and played a couple of vids for a minute or two. Nothing else I can think of and no phone calls made. The fully charged battery this morning was giving me low battery status by the afternoon. Wtf? This is the 900 mAh one that came with it.

I last a full day with frequent internet/video/game use. maybe 2.5 hours of that stuff, 1 hour of text messaging, 1 hour of phone calls, 30 minutes of just dicking around, and the rest of the time with it in on in my pocket.
there's a bigger battery available - the model is "BP E270"

well with stock battery i was able to watch 2hour film...than battery was at 10% from fully charged..so battery is disaster....

if you would convert video for hardware accelration - it would not use 90% of battery, only 40% )

if you use a different ROM, some are more efficient with battery life.
also, there are third party batteries as big as 1800 mAh. be warned that this is just the manufacturer's claim and they're usually made in China. I think a site called dealextreme has it for the cheapest but there's a ton of different versions on the net. most bigger batteries come with a bigger back plate to accommodate the extra size. most do not have the "diamond" detailing.

I've got the 1800mAh Cameron Sino and it works brilliantly. I can leave the Wifi on all day, make calls, browse the internet without too much worry of the battery giving out half way through the day. With the origonal battery (900mAh) I practically gave up on the phone and used a Nokia E51 instead. The only downside to the new back cover is as tacky as hell and you need to put some tin foil over the GPS Antenna for it to work.
However, I can actually use the phone now on a day to day basis. Oh and the phone stands on its side now due to the extra thickness so I can watch TV progs etc without holding it.

I might try for a more powerful battery but not one of those oversized ones with bigger backplate. And I'm not sure I'm ready to risk a different rom, I'd frankly be bricking 'bricking' it.
What amazes me is, why did htc supply such a weak 900mAh battery in a phone which undoubtedly requires MUCH more power than say, my artemis, and that came with a 1200mAh battery. Doesn't make sense.

i am converting films for hw acceleration,i use mp4 for hd to convert them and than i use htc album to wact movie....and battery is disaster
also i am using nuedynamicclock but it only helps at night(it should help also when ppc is on cause i reduced voltage for 528MHz(from 1.35v to 1.1v),and i am using rom that is tweaked for minimal battery usage...it helps a little bit but not enough
900mAh is way to low for this device...
also if i want to buy new battery i need also new backplate so my diamond will be fatter???
