My phone has burned out 2 new batteries in less than 8 months. It shortens their charge life until they only stay charged 4 hours on standby. I replace the batteries but the batteries aren't the problem. The phone discharges and depletes the batteries. I'm told this is a standard problem with RAZRs and that Motorola will send you a replacement phone if the phone is less than a year old. I can't get a reply from Motorola.

If there is no visual indication built in then you won't know but a guesstimate will be found in the operating instructions from the recommended charging time and the time it operates from a full charge.
If the device uses lithium ion batteries it is better to charge little and often rather than wait until they are discharged. The life of lithium ion batteries is shortened by the heating of long charge times and being fully charged - not discharging to less than 30% capacity and not charging to more than 80% will ensure the batteries last longer...
It's not the charger, it's the battery pack. The way phones are wired, power goes to the battery pack first and then to the phone electronics. If the battery is more than 18 months old and you keep it plugged in a lot; i.e., don;t allow the phone's battery to discharge near empty each time then battery life will be shortened. Keep phones in temperature extremes will have the same effect. Would recommend you consider getting one of those emergency chemical batteries for your cell phone and try that first before shelling out the bucks for a new NimH battery. (Remember, phone companies don;t make batteries... most are made by Mashushita (Panasonic) or Sanyo (bought out GE's rechargable battery business many years ago.) This may help you locate less expensive OEM batteries for your phone.
1. Turn off your phone when it's not in use. If you're not using your Verizon Wireless Razr, then shut it off. Your battery will last much longer if you regularly do this. 2. Charge your phone less. If you charge your Razr nightly, then your cell phone battery won't last long. Try to charge your phone only a few times a week to extend the battery life. 3. Keep your Bluetooth turned off when you're not using it. Applications, like Bluetooth, are notorious for sucking the power from a cell phone battery. 4. Protect your Razr from extreme temperatures. Your cell phone battery lasts longer if kept at room temperature. 5. Discharge the Razr fully. Before you charge your phone, let it completely die. You can extend the life of the battery by regularly discharging and then fully charging it. 6. Leave the battery in the phone. Keep the Razr battery dry and free of dirt to prolong its life.
If the cell phone battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% and graduallythe charge reduces until the battery won't charge up at all. OR The batteryshows a 100% charge but when the adapter is disconnected the battery drops offto zero capacity in a very short time. If the battery drops to an unacceptablecharge level then the battery needs to be replaced.
Has the battery been fully discharged (used until it will not power up the item) very many times? This is very bad for Li/Po batteries. If the phone is less than 6-12 months old, I would contact my cell provider and ask for a replacement battery. In lieu of your provider replacing it, your only option will likely be to replace it yourself. Unlike the old-school Ni/Cad rechargeable batteries, Li/Po batteries lose their ability to hold a charge if they are drained fully too many times. Also a good tip with a new battery is to charge it longer than just until the battery power indicator is full (overnight is a good basic rule, but check your phone's user guide or google the specific battery model for recommended charge times) for the first few charges, and avoid letting it fully discharge. Try to get it on a charger with at least 1 or 2 bars left. This will increase the life of a cell phone battery dramatically.
Sadly phone batteries don't have the long life they used too. There isn't a lot you can do besides purchase a new battery. Samsung only covers the battery for one year from date of purchase, so you might be able to get a replacement if you have had it for less than a year. Otherwise, eBay is your friend. You can extend the life of the battery by changing some habits of how you use the device.
- Let the battery run completely down about (dead phone) about once a month. This helps ensure a longer life.
- Try to avoid using car chargers. The power provided isn't always the most stable and can greatly shorten the life of your battery.
Once you get a new battery, don't charge it right away. Let it run down the first time to empty before first time charge. That will ensure a long, healthy battery life.
by keeping the player constantly plugged in when of will have seriously shortened the battery life, rechargeable batteries ( exept the very latest ones) perform best by charging then using until fully discharged and charging again. this will ensure your battery lasts a long time, constantly charging a half charged battery will shorten the batteries life.
