Ere are a few things that might be causing your battery life woes, though I would have thought a new battery should last longer than three weeks before noticeably slowing down.

The biggest killer for batteries is heat, so I must ask are you in a hot part of the world? Lithium-ion batteries rely on a chemical reaction to charge. As you may remember from high school chemistry, if a chemical reaction does not fully consume all available reagents, it will create byproducts instead — and sometimes those byproducts are undesirable.

As such, if you charge a faulty lithium-ion battery, the process generates gas rather than simply charging. This gas builds up over time, and since batteries are hermetically sealed, they expand rather than vent. And if you keep charging and charging, the battery will eventually burst — and potentially explode. In fact, the odds are against it on a charge-by-charge basis. By way of disclaimer, I can only speak from my own experience as the owner of a Motorola phone with a Verizon Wireless plan.

But any manufacturer and wireless carrier should provide similar services to what's described below, so you should have most of the same options at your disposal. I tweeted at the Motorola support account , where a customer-service rep gave me some good advice. My product was out of warranty, but Motorola could still potentially fix it for a price. We will update this piece once we hear back from them. A deep discharge condition can also create safety hazards.

When a lithium-ion cell goes into deep discharge, it is in a highly de-intercalated state The word intercalate means to insert between layers in a crystal lattice. When the battery is deep discharged, the protective passivation layer on the anode called the Solid Electrolyte Interphase SEI layer decomposes, with new electrode and electrolyte surfaces coming in contact and new SEI layer is formed.

All of these reactions lead to gas formation. The copper current collector on the negative electrode also starts to dissolve as shown in Figure 2. Upon recharge these copper ions deposit on electrode or separator surfaces potentially leading to a copper short and the risk of thermal runaway Battery folks call this an event, while normal folks call this an explosion. Such a deeply discharged battery should not be recharged and a deep discharge voltage cutoff must be implemented in the battery protection system by the device manufacturer.

This can include a trickle charge till a certain threshold voltage is reached within a given time and ramping up charge subsequently. Failure to reach the voltage threshold in the given time, would classify the battery as damaged and shut it down, preventing it from being used. What can you do as a consumer to prevent a bloated battery situation? Do not buy cheap batteries, where you are not in a position to assess cell manufacturing quality.
