HTC EVO 4G : Do Batteries Have Good - Bad Days?
Jun 29, 2010
No, this is not a thread to bash the battery for the EVO. In fact if you do some research, you will notice that i have praised the EVO's battery in the past. Recently, however, my battery died on me on my trip to florida, and a sprint store in Daytona ordered me a new one. It is not the red EVO battery i have come to know, but a mere black one with the words 'HTC Innovations', and has the appearance of it looking used (some crud on it, which i still have not removed).
So my question is do batteries have good and bad days? I have not changed any settings on my phone, and i use to get a day out of it before it reaching 20%. Now im lucky to get 6 hours. Did i get a refurbished battery?

I was looking for batteries for my EVO in Ebay and saw those 2700 mAh batteries with c overs. Did anybody try them? Are they any good?

I'm looking to buy a spare battery, and atm, i'm leaning towards buying an oem battery. But before I make a purchase, I'd like to hear some first hand experiences from actual owners of slim extended batteries. So, if you don't mind, those of you who actually use the extended slim batteries, please let me know the company, mah, where you bought it from, and you experiences.

No matter what I do I am unable to open a file, either in my app's data directory or on the sdcard and also in a folder on the sdcard. To test I placed a test.txt file in all three directories.When I do listfiles, I get the correct list of files set in an array. I've even tried getting the list and filtering out a specific file and try opening it that way and just trying the first item in the array.Is there some security that may be set that is making it so I cant open files? This is not the emulator, it is on a device.

Doesn't have to be HTC branded, as long as it's form a reputable source?

Make an internal battery to run on, and a battery you can slide in and out like a SD card so you don't have to keep shutting down, restarting the phone and pulling off the battery cover just cause your phone has bad battery life.. aren't cameras this way? I could swear my kodak was like this.

Is it just me or are there no cases once you get an extended battery. Sendo adds 4mm and the OEM adds 1mm. I am guessing that you have the choice between the battery or a case. I wonder if a flexible case like the tough case would have a problem with a 1mm difference. Sent from my Incredible using Tapatalk

I'm getting a ton more time out of the batteries charged in the wall charger but I have noticed the batteries won't charge in the phone via USB. Anyone else have this problem? I like the extra time but not being able to charge in anything except the wall isn't that great. Guess i'll just use them as backup batteries.

Is there any way to put this phone into a PHONE ONLY mode? The idea here is to turn off all Android functions and have it operate as only a phone, calls and texts only. The idea here would be to maximize battery life if you know that you are going to be away from power for a long time, and want to be sure you can use the phone if an emergency arises.

I live in India and unfortunately mobilefun.co.uk as well as htcpedia do not ship to India
Came across a deal on Ebay UK for an OEM Nexus One battery 1400mAH. Does it work on the Desire?
Btw, last week i have already ordered a non-oem battery+cradle charger off ebay. are non-oem batteries reliable?

That message has been popping up intermittently on my Droid since day one. I've gone through the Exchange email set up a dozen times (since it keeps disappearing.)I have swapped out my Droid for a new one.I've done factory hard resets.I typically receive 200+ Exchange emails daily and my Droid is receiving about 10% of these.I've verified with our I.T. Dept. all settings are correct - there are 40+ Droid users here and I'm the only one experiencing this ongoing problem.Can anyone help?I spoke with someone who works for Moto, and they denied any knowledge of this problem.I'd hate to think this is an over-priced paperweight.

* Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.
* Batteries with fuel gauge (laptops) should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely.
* Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.
* Consider removing the battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)
* Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.
* If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the battery at 40% state-of-charge.
Several partial discharges with frequent recharges are better for lithium-ion than one deep one.
I can said portable solar charger (built in large capacity li-ion battery) is a better emergency solution for most consumer electronics. Solar Battery Charger --- Give timely additional juice to Phone Battery
Try this. SimeniBiz - 3500mAh solar charger, compatible the most digital device.

So, I don't know where the thread went, but I know we where all pissed off a out only getting a 1500mAh battery, but according to Seidio its a 1750mAh, which is a huge update from a 1300mAh, me thinks.
Not that I've figured out how to get 12 hours out of my Eris Moderate-Heavy use, but this should only make things better. I think the 3500mAh is a bit ridiculous.
Let this be the thread to discuss these add on batteries, and either their positive or negative effects on your life.
Assuming that the Nexus One or anything like it is not coming to VZ anytime soon, I'm happily ordering one of these and ready to roll on with my Eris http://www.seidioonline.com/product-p/basi17hhrv.htm

I noticed something 2 days ago by accident. After I charged my Ozone battery in my Ozone phone, I place it in my Eris. The battery read 100% for 2 hours. When I charge it in the Eris, it immediately starts to drop. Is the Eris charging the battery at less than full capacity?

There has been considerable disparity regarding Droid users battery life post update. I was one reporting very disappointing results. My phone usually would come off the charger at 6AM and down to 20% by noon with moderate use. I went out and bought a new battery and my phone went till about PM yesterday before I hit 20%. Went back to the old battery and again I'm. nearly drained by 2PM. Clearly my two batteries discharge at different rates. This probably explains why people are describing such different results.

I'm close to my 30 days trial being up and I will be out of town when it actually is, so I needed to return the phone early. I just can't live without a working GPS function on a SmartPhone. I travel and love how smartphones allow to me to schlep on less thing (GPS).
Anyway, I had ordered the Ebay Hongkong 2 batteries & charger. Since I have no use for them I'm going to give them away. They are $10 new so by the time I list them and have them sold on ebay its just not worth the hassle.
The first person with over 30 posts who responds to this thread will get them free of charge. I'm going to send them to you on the honor system. After you get them, please compensate me for the postage. Lower 48 USA only please.
I hope this isn't violating any forum rules, but since I'm giving these away, not selling them I should be ok.

Before I even ordered my Incredible I ordered a stand alone battery charger and two extra batteries direct from a China supplier on e bay for $14 total. These batteries are Atomic! I'm getting 50% more running time out of them than the factory battery no lie. The batteries are marked HTC Touch Pro 2 but fit the Incredible also.

I emailed HTC last week with these questions, thought I would post up the replies if anyone else wants to know...
1) Is this safe to use 3rd party extended batteries and will it make a difference to the capacity (it's 1600mAh)? Also, are HTC going to release an official extended battery in the near future?
2) When will the copy protection issue with Google get sorted out?
3) Are you going to release a version of HTC Sync for the Mac operating system?

I did search and read the other threads, but has anyone had experience with portable chargers with the Eris?
I am headed to Bonnaroo and I am sure I'll be using the phone a lot so I was looking at the smaller portable chargers that run off of AA batteries. Figuring I'll need a mid day charge so I want a smaller one to throw in my pack.

I'm using a Droid X, and I bought a spare battery so I can go all day wihtout a fill up so to speak. However I'm noticing that whenever I place a one of the other batteries in, it gives me the same reading as the last battery that was in it, no matter what. Any way to fix this?

I am trying to find a calendar app that will allow me to scroll through calendar days. The android app looks great but makes me crazy. If I am trying to schedule something more than a week out and want to be able to see all events day by day I have to click on a day then click out and then click on the next day. Is there a way I can just scroll?

What is the easiest way to get FB birthdays to sync onto my calendar. I've seen a few things online, but seeing that we have HTC sense, there must be an easier way. I mean...all the birthdays are in the people app.

I have to repeat alarm for between 1 day to 60 days. For example, the user can be able to repeat alarm after every 5 days, 10 days or 60 days (maximum).
Option1 ( Implemented Code
alarmmanager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()+ (durationInDays * 24 * 3600 * 1000), (durationInDays * 24 * 3600 * 1000), pIntent);
Note: But it is working fine but it supports maximum 10 days(appx) repeating only after that "(durationInDays * 24 * 3600 * 1000)" it goes into -ve value so, I am unable to set maximum 60 days alarm repeatedly. AlarmManager class only supports a long value for choosing the interval between the execution of the pending intent.
Is there any other option to set repeat alarm for the no of days ?
Option 2 ( Implemented Code:
Date futureDate = new Date(new Date().getTime() + (86400000 * durationInDays));
Date dateInterval = new Date(86400000 * durationInDays);
am.setRepeating(AlarmManager.RTC_WAKEUP, futureDate.getTime(), dateInterval.getTime(), pendingIntent);
Note: We set repeating alarm maximum every 24 days but when i give (durationInDays = 25; // in Days) then it takes -ve values.
Can I set repeating alarm with Calender?
