E-9-1-1 helps find an accident victim

I wouldn't put it that way. There are many GSM phones that have shameful battery life and CDMA phones that have good battery life. Take for instance the GSM Motorolas. Pretty much all of them have poor battery life ranging from one to two days at most with some people that can reach 3 days without recharging because they barely touch the phone. However, there are exceptions. No CDMA phone can last 3 or 4 days of regular use on a 800mAh battery like some GSM phones do (the SE T616 comes to mind). This is why in the CDMA world it is more common to see extended batteries for sale.

 

As long as the battery lasts a full day I really don't care. I also use the battery hogging bluetooth, and its always on. The new phones are far better than the old ones. I remember toward the end my StarTac was only lasting about 4-6 hours on a charge.

I use my RAZR, on Cingular, with my Jabra bluetooth headset for about 9 to 10 hours a day and when I go to bed they all go back on the charger and I have never seen my phone lose even 1 bar of battery life. Now let me clarify as I reread my post, I do not talk for 9 to 10 hours a day but my bluetooth Jabra is connected for 9 to 10 hours and I probably make/receive about 10 or so calls during that 9 to 10 hours (maybe 2 to 3 minutes average per call). I have been doing this now for the last week and a half and so far my phone, unless it is defective, has never lost a bar on the battery meter. Pretty good in my opinion as I thought bluetooth was a battery hog but all I need out of a phone and earpiece is morning to night and then it gets recharged.

 

Exactly. Its nice if you're camping in the woods and you can't charge your phone, (But who uses a cell phone camping? The point of camping is to get away from it all) but to me I don't need a phone that lasts a week between charges. My cell phone is on 24/7/365. I never turn it off, I just powercycle it once a week to update the PRL and any other OTA updates that were sent to the phone. I usually plug in my phone and BT headset every night. If I forget to charge at night it usually lasts through the second day, but I never know how much I'm going to talk on the phone on any given day. Sometimes I spend all day on the phone, and others I may not even use it at all. I try to keep my phone charged every night so I am ready for whatever the day throws at me. If I disable BT then the battery will last 3-4 days, but then I am stuck holding the handset! I have BT so I don't have to do that!

My GSM Phone has a Longer Battery Life
than my CDMA phone because GSM has a Battery Saver.
The CDMA phone would always die first than a GSM Phone
even if they where Charge at the Same time.
Those that have used both Technology could Verify this.

 

Don't CDMA phones have a higher power output than GSM phones? That is the case with AMPS since the phone needs to transmit at a higher rate.

 

I think the power output is the same, it is how it is utilized that uses up the battery.

You could keep your Bluetooth headset connected all day to your phone and it won't make a dent in your battery if you don't use it. Bluetooth doesn't really use any power if it is not being used. In the days I use my Bluetooth headset, I use it all day, 9 or 10 hours like you and it doesn't make any difference in my phone's battery life. I still have to charge it every night. Now, Bluetooth will eat your phone's battery quicker if you are on phone calls constantly. But with phone calls that last 2 or 3 minutes, that's barely any usage.

To me, a phone that has to go in the charger every night under regular phone-only usage has poor battery life. This becomes a problem for me when my nephew wants to borrow the phone to play games on it (no more than 15 minutes) or when I want to check something quickly on the Internet (again 10 or 15 minutes of use). The extra drain these activities place on the battery means that before I know it I have to rush the phone to the emergency charger in critical condition before the day is over. To me that's not reliable. I want a phone that can take all that unexpected usage and you can only get that from a phone that can go at least 3 days under regular everyday phone-only usage, so that when it is placed under heavy usage (internet/playing games) at least the phone makes it to the end of the night. So it has nothing to do with going camping. It's just that I need a phone that can go the extra mile when I need it. It's about peace of mind that your battery is not going to die when you need the phone the most.

Sometimes I go on trips out of town and that's when I use the internet in my phone the most because I am away from my computer. With my phone, I have to keep internet usage a minimum otherwise I have to plug in the charger before I know it.

I guess I am used to the good-old TDMA Nokia phones that could go a whole weekend without worrying about the charger. I remember I was able to put my charger away in my closet forever because I only charged my phone in the car every 3 or 4 days. That's what I call good battery life! But now, with large color screens, cameras, tons of games, speakerphone, MP3s, and tons of things you can do with the phones, we don't have that luxury anymore. Phone manufacturers have gone crazy adding features to phones, but have done little to compensate for the increased use in power. This has caused the general degradation in battery life. If you recall, phones in the late 90's/early 2000's used to have the same battery charge (or more) that they have today, ranging in the 700mAh to 900mAh. Extended batteries were higher than that. But while an old monochrome Nokia with no fancy features, no camera or nothing else would last 4 or 5 days on a 900mAh battery, they are still using the same 900mAh to power a phone that has everything from a camera to video player, to MP3 player, etc. So of course the battery life won't be the same!

However, I find it amazing how Sony Ericsson can do so much better than Motorola packing more power in a smaller battery and making phones that are more efficient, smaller and faster with virtually the same features and last about 3 times the life per charge of a Motorola. If you compare the Moto V635 with the Sony Ericsson z520, the battery in the Motorola is larger than the one in the z520, yet the z520 is 900mAh while the Motorola is 780mAh. Also, the battery consumption on the z520 is much less giving an impressive difference in battery life.

I find it hard to believe that SE can make a more efficient phone than Motorola at a far cheaper price.

 

Actually, GSM phones have higher power output. The maximum for GSM is 2000mW at 850/900Mhz and 1000mW at 1800/1900Mhz. For CDMA, it shouldn't exceed 600mAh for any band.

The extra battery consumption comes from the extra processing power that CDMA needs. So with UMTS/HSDPA the days of the GSM battery life advantage are numbered!

 

My Nokia 6230 phone is on 24/7, getting charged only about 1 hour in the car each day. If I don't charge it that way, and with bluetooth on, it lasts about 3 days and gets to about 1/4 power. I only use bluetooth for texting with my PC.

 

Cool,

you learn something new every day. So my statement about AMPS having the higher power output is correct, then?
